Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117128, here are decompositions:

  • 19 + 117109 = 117128
  • 139 + 116989 = 117128
  • 199 + 116929 = 117128
  • 331 + 116797 = 117128
  • 337 + 116791 = 117128
  • 397 + 116731 = 117128
  • 409 + 116719 = 117128
  • 421 + 116707 = 117128

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 117,128 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 117128 first appears in π at position 762,588 of the decimal expansion (the 762,588ordinal-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.
