Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157078, here are decompositions:

  • 17 + 157061 = 157078
  • 29 + 157049 = 157078
  • 41 + 157037 = 157078
  • 59 + 157019 = 157078
  • 71 + 157007 = 157078
  • 107 + 156971 = 157078
  • 137 + 156941 = 157078
  • 179 + 156899 = 157078

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 157,078 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 157078 first appears in π at position 203,307 of the decimal expansion (the 203,307ordinal-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.
