Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171826, here are decompositions:

  • 3 + 171823 = 171826
  • 23 + 171803 = 171826
  • 107 + 171719 = 171826
  • 113 + 171713 = 171826
  • 167 + 171659 = 171826
  • 173 + 171653 = 171826
  • 197 + 171629 = 171826
  • 353 + 171473 = 171826

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 171,826 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 171826 first appears in π at position 445,724 of the decimal expansion (the 445,724ordinal-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.
