Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151964, here are decompositions:

  • 61 + 151903 = 151964
  • 67 + 151897 = 151964
  • 151 + 151813 = 151964
  • 181 + 151783 = 151964
  • 193 + 151771 = 151964
  • 271 + 151693 = 151964
  • 277 + 151687 = 151964
  • 283 + 151681 = 151964

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 151,964 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 151964 first appears in π at position 684,012 of the decimal expansion (the 684,012ordinal-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.
