Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171458, here are decompositions:

  • 19 + 171439 = 171458
  • 31 + 171427 = 171458
  • 367 + 171091 = 171458
  • 379 + 171079 = 171458
  • 409 + 171049 = 171458
  • 487 + 170971 = 171458
  • 571 + 170887 = 171458
  • 577 + 170881 = 171458

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 171,458 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 171458 first appears in π at position 933,425 of the decimal expansion (the 933,425ordinal-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.
