Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127982, here are decompositions:

  • 3 + 127979 = 127982
  • 31 + 127951 = 127982
  • 61 + 127921 = 127982
  • 109 + 127873 = 127982
  • 139 + 127843 = 127982
  • 163 + 127819 = 127982
  • 271 + 127711 = 127982
  • 313 + 127669 = 127982

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 127,982 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 127982 first appears in π at position 174,868 of the decimal expansion (the 174,868ordinal-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.
