Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178862, here are decompositions:

  • 3 + 178859 = 178862
  • 31 + 178831 = 178862
  • 43 + 178819 = 178862
  • 109 + 178753 = 178862
  • 181 + 178681 = 178862
  • 223 + 178639 = 178862
  • 241 + 178621 = 178862
  • 331 + 178531 = 178862

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 178,862 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 178862 first appears in π at position 640,641 of the decimal expansion (the 640,641ordinal-suffix:st 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.
