Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118730, here are decompositions:

  • 13 + 118717 = 118730
  • 43 + 118687 = 118730
  • 61 + 118669 = 118730
  • 97 + 118633 = 118730
  • 109 + 118621 = 118730
  • 127 + 118603 = 118730
  • 181 + 118549 = 118730
  • 277 + 118453 = 118730

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 118,730 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 118730 first appears in π at position 615,926 of the decimal expansion (the 615,926ordinal-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.
