Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115800, here are decompositions:

  • 7 + 115793 = 115800
  • 17 + 115783 = 115800
  • 19 + 115781 = 115800
  • 23 + 115777 = 115800
  • 29 + 115771 = 115800
  • 31 + 115769 = 115800
  • 37 + 115763 = 115800
  • 43 + 115757 = 115800

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 115,800 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 115800 first appears in π at position 644,558 of the decimal expansion (the 644,558ordinal-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.
