Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169518, here are decompositions:

  • 17 + 169501 = 169518
  • 29 + 169489 = 169518
  • 47 + 169471 = 169518
  • 61 + 169457 = 169518
  • 109 + 169409 = 169518
  • 149 + 169369 = 169518
  • 157 + 169361 = 169518
  • 179 + 169339 = 169518

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 169,518 and was likely granted around 1874.

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

Position in π

The digit sequence 169518 first appears in π at position 203,687 of the decimal expansion (the 203,687ordinal-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.
