Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127750, here are decompositions:

  • 3 + 127747 = 127750
  • 11 + 127739 = 127750
  • 17 + 127733 = 127750
  • 23 + 127727 = 127750
  • 41 + 127709 = 127750
  • 47 + 127703 = 127750
  • 59 + 127691 = 127750
  • 71 + 127679 = 127750

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 127,750 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 127750 first appears in π at position 970,124 of the decimal expansion (the 970,124ordinal-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.
