Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157306, here are decompositions:

  • 3 + 157303 = 157306
  • 29 + 157277 = 157306
  • 47 + 157259 = 157306
  • 53 + 157253 = 157306
  • 59 + 157247 = 157306
  • 89 + 157217 = 157306
  • 173 + 157133 = 157306
  • 179 + 157127 = 157306

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 157,306 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 157306 first appears in π at position 617,120 of the decimal expansion (the 617,120ordinal-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.
