Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157328, here are decompositions:

  • 7 + 157321 = 157328
  • 37 + 157291 = 157328
  • 97 + 157231 = 157328
  • 109 + 157219 = 157328
  • 139 + 157189 = 157328
  • 151 + 157177 = 157328
  • 271 + 157057 = 157328
  • 277 + 157051 = 157328

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 157,328 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 157328 first appears in π at position 59,115 of the decimal expansion (the 59,115ordinal-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.
