Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115868, here are decompositions:

  • 7 + 115861 = 115868
  • 19 + 115849 = 115868
  • 31 + 115837 = 115868
  • 37 + 115831 = 115868
  • 61 + 115807 = 115868
  • 97 + 115771 = 115868
  • 127 + 115741 = 115868
  • 211 + 115657 = 115868

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 115,868 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 115868 first appears in π at position 515,918 of the decimal expansion (the 515,918ordinal-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.
