Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171626, here are decompositions:

  • 43 + 171583 = 171626
  • 67 + 171559 = 171626
  • 73 + 171553 = 171626
  • 97 + 171529 = 171626
  • 109 + 171517 = 171626
  • 157 + 171469 = 171626
  • 199 + 171427 = 171626
  • 223 + 171403 = 171626

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 171,626 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 171626 first appears in π at position 658,423 of the decimal expansion (the 658,423ordinal-suffix:rd 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.
