Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127816, here are decompositions:

  • 53 + 127763 = 127816
  • 83 + 127733 = 127816
  • 89 + 127727 = 127816
  • 107 + 127709 = 127816
  • 113 + 127703 = 127816
  • 137 + 127679 = 127816
  • 167 + 127649 = 127816
  • 173 + 127643 = 127816

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 127,816 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 127816 first appears in π at position 865,894 of the decimal expansion (the 865,894ordinal-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.
