Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186510, here are decompositions:

  • 29 + 186481 = 186510
  • 31 + 186479 = 186510
  • 41 + 186469 = 186510
  • 59 + 186451 = 186510
  • 73 + 186437 = 186510
  • 113 + 186397 = 186510
  • 131 + 186379 = 186510
  • 167 + 186343 = 186510

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 186,510 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 186510 first appears in π at position 564,442 of the decimal expansion (the 564,442ordinal-suffix:nd 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.
