Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157310, here are decompositions:

  • 3 + 157307 = 157310
  • 7 + 157303 = 157310
  • 19 + 157291 = 157310
  • 31 + 157279 = 157310
  • 37 + 157273 = 157310
  • 67 + 157243 = 157310
  • 79 + 157231 = 157310
  • 103 + 157207 = 157310

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 157,310 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 157310 first appears in π at position 182,554 of the decimal expansion (the 182,554ordinal-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.
