Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157160, here are decompositions:

  • 19 + 157141 = 157160
  • 79 + 157081 = 157160
  • 103 + 157057 = 157160
  • 109 + 157051 = 157160
  • 181 + 156979 = 157160
  • 193 + 156967 = 157160
  • 337 + 156823 = 157160
  • 379 + 156781 = 157160

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 157,160 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 157160 first appears in π at position 360,703 of the decimal expansion (the 360,703ordinal-suffix:rd 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.
