Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178814, here are decompositions:

  • 7 + 178807 = 178814
  • 61 + 178753 = 178814
  • 193 + 178621 = 178814
  • 211 + 178603 = 178814
  • 277 + 178537 = 178814
  • 283 + 178531 = 178814
  • 313 + 178501 = 178814
  • 367 + 178447 = 178814

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 178,814 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 178814 first appears in π at position 390,283 of the decimal expansion (the 390,283ordinal-suffix:rd 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.
