Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186318, here are decompositions:

  • 7 + 186311 = 186318
  • 17 + 186301 = 186318
  • 19 + 186299 = 186318
  • 47 + 186271 = 186318
  • 59 + 186259 = 186318
  • 71 + 186247 = 186318
  • 79 + 186239 = 186318
  • 89 + 186229 = 186318

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 186,318 and was likely granted around 1875.

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

Position in π

The digit sequence 186318 first appears in π at position 189,324 of the decimal expansion (the 189,324ordinal-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.
