Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127908, here are decompositions:

  • 31 + 127877 = 127908
  • 41 + 127867 = 127908
  • 59 + 127849 = 127908
  • 71 + 127837 = 127908
  • 89 + 127819 = 127908
  • 101 + 127807 = 127908
  • 127 + 127781 = 127908
  • 181 + 127727 = 127908

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 127,908 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 127908 first appears in π at position 303,467 of the decimal expansion (the 303,467ordinal-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.
