Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171550, here are decompositions:

  • 11 + 171539 = 171550
  • 59 + 171491 = 171550
  • 83 + 171467 = 171550
  • 101 + 171449 = 171550
  • 149 + 171401 = 171550
  • 167 + 171383 = 171550
  • 233 + 171317 = 171550
  • 251 + 171299 = 171550

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 171,550 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 171550 first appears in π at position 143,754 of the decimal expansion (the 143,754ordinal-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.
