Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172700, here are decompositions:

  • 13 + 172687 = 172700
  • 19 + 172681 = 172700
  • 37 + 172663 = 172700
  • 43 + 172657 = 172700
  • 67 + 172633 = 172700
  • 97 + 172603 = 172700
  • 103 + 172597 = 172700
  • 127 + 172573 = 172700

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 172,700 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 172700 first appears in π at position 394,229 of the decimal expansion (the 394,229ordinal-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.
