Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126826, here are decompositions:

  • 3 + 126823 = 126826
  • 83 + 126743 = 126826
  • 107 + 126719 = 126826
  • 113 + 126713 = 126826
  • 173 + 126653 = 126826
  • 353 + 126473 = 126826
  • 383 + 126443 = 126826
  • 467 + 126359 = 126826

Showing the first eight; more decompositions exist.

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 126,826 and was likely granted around 1872.

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

Position in π

The digit sequence 126826 first appears in π at position 42,446 of the decimal expansion (the 42,446ordinal-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.
