Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172910, here are decompositions:

  • 43 + 172867 = 172910
  • 61 + 172849 = 172910
  • 103 + 172807 = 172910
  • 109 + 172801 = 172910
  • 151 + 172759 = 172910
  • 193 + 172717 = 172910
  • 223 + 172687 = 172910
  • 229 + 172681 = 172910

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 172,910 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 172910 first appears in π at position 180,608 of the decimal expansion (the 180,608ordinal-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.
