Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178876, here are decompositions:

  • 3 + 178873 = 178876
  • 17 + 178859 = 178876
  • 23 + 178853 = 178876
  • 59 + 178817 = 178876
  • 83 + 178793 = 178876
  • 179 + 178697 = 178876
  • 233 + 178643 = 178876
  • 263 + 178613 = 178876

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 178,876 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 178876 first appears in π at position 269,494 of the decimal expansion (the 269,494ordinal-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.
