Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115740, here are decompositions:

  • 7 + 115733 = 115740
  • 13 + 115727 = 115740
  • 47 + 115693 = 115740
  • 61 + 115679 = 115740
  • 83 + 115657 = 115740
  • 103 + 115637 = 115740
  • 109 + 115631 = 115740
  • 127 + 115613 = 115740

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 115,740 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 115740 first appears in π at position 776,529 of the decimal expansion (the 776,529ordinal-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.
