Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157910, here are decompositions:

  • 3 + 157907 = 157910
  • 13 + 157897 = 157910
  • 43 + 157867 = 157910
  • 73 + 157837 = 157910
  • 79 + 157831 = 157910
  • 97 + 157813 = 157910
  • 139 + 157771 = 157910
  • 163 + 157747 = 157910

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 157,910 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 157910 first appears in π at position 470,246 of the decimal expansion (the 470,246ordinal-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.
