Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022446, here are decompositions:

  • 3 + 1022443 = 1022446
  • 17 + 1022429 = 1022446
  • 59 + 1022387 = 1022446
  • 197 + 1022249 = 1022446
  • 263 + 1022183 = 1022446
  • 317 + 1022129 = 1022446
  • 647 + 1021799 = 1022446
  • 653 + 1021793 = 1022446

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 2446 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2446-02-01 (DMMYYYY (Euro, single-digit day))
  • 2446-10-02 (MMDYYYY (US, single-digit day))
  • 2446-02-10 (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 1,022,446 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 1022446 first appears in π at position 219,649 of the decimal expansion (the 219,649ordinal-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.
