Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127966, here are decompositions:

  • 53 + 127913 = 127966
  • 89 + 127877 = 127966
  • 107 + 127859 = 127966
  • 149 + 127817 = 127966
  • 227 + 127739 = 127966
  • 233 + 127733 = 127966
  • 239 + 127727 = 127966
  • 257 + 127709 = 127966

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 127,966 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 127966 first appears in π at position 70,475 of the decimal expansion (the 70,475ordinal-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.
