Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022380, here are decompositions:

  • 3 + 1022377 = 1022380
  • 89 + 1022291 = 1022380
  • 131 + 1022249 = 1022380
  • 137 + 1022243 = 1022380
  • 179 + 1022201 = 1022380
  • 197 + 1022183 = 1022380
  • 239 + 1022141 = 1022380
  • 251 + 1022129 = 1022380

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 2380 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2380-02-01 (DMMYYYY (Euro, single-digit day))
  • 2380-10-02 (MMDYYYY (US, single-digit day))
  • 2380-02-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,022,380 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1022380 first appears in π at position 476,957 of the decimal expansion (the 476,957ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
