Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178736, here are decompositions:

  • 43 + 178693 = 178736
  • 97 + 178639 = 178736
  • 109 + 178627 = 178736
  • 127 + 178609 = 178736
  • 139 + 178597 = 178736
  • 199 + 178537 = 178736
  • 223 + 178513 = 178736
  • 409 + 178327 = 178736

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 178,736 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 178736 first appears in π at position 675,877 of the decimal expansion (the 675,877ordinal-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.
