Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126916, here are decompositions:

  • 3 + 126913 = 126916
  • 59 + 126857 = 126916
  • 89 + 126827 = 126916
  • 173 + 126743 = 126916
  • 197 + 126719 = 126916
  • 233 + 126683 = 126916
  • 263 + 126653 = 126916
  • 443 + 126473 = 126916

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 126,916 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 126916 first appears in π at position 402,312 of the decimal expansion (the 402,312ordinal-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.
