Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171512, here are decompositions:

  • 31 + 171481 = 171512
  • 43 + 171469 = 171512
  • 73 + 171439 = 171512
  • 109 + 171403 = 171512
  • 241 + 171271 = 171512
  • 349 + 171163 = 171512
  • 409 + 171103 = 171512
  • 421 + 171091 = 171512

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 171,512 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 171512 first appears in π at position 767,296 of the decimal expansion (the 767,296ordinal-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.
