Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157908, here are decompositions:

  • 7 + 157901 = 157908
  • 11 + 157897 = 157908
  • 19 + 157889 = 157908
  • 31 + 157877 = 157908
  • 41 + 157867 = 157908
  • 67 + 157841 = 157908
  • 71 + 157837 = 157908
  • 109 + 157799 = 157908

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 157,908 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 157908 first appears in π at position 831,128 of the decimal expansion (the 831,128ordinal-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.
