Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018392, here are decompositions:

  • 79 + 1018313 = 1018392
  • 83 + 1018309 = 1018392
  • 101 + 1018291 = 1018392
  • 139 + 1018253 = 1018392
  • 191 + 1018201 = 1018392
  • 269 + 1018123 = 1018392
  • 283 + 1018109 = 1018392
  • 373 + 1018019 = 1018392

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 8392 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8392-10-01 (MMDYYYY (US, single-digit day))
  • 8392-01-10 (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 1,018,392 and was likely granted around 1911.

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

Position in π

The digit sequence 1018392 first appears in π at position 350,651 of the decimal expansion (the 350,651ordinal-suffix:st 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.
