Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178322, here are decompositions:

  • 61 + 178261 = 178322
  • 73 + 178249 = 178322
  • 139 + 178183 = 178322
  • 181 + 178141 = 178322
  • 229 + 178093 = 178322
  • 283 + 178039 = 178322
  • 373 + 177949 = 178322
  • 379 + 177943 = 178322

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 178,322 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 178322 first appears in π at position 232,697 of the decimal expansion (the 232,697ordinal-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.
