Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178936, here are decompositions:

  • 3 + 178933 = 178936
  • 5 + 178931 = 178936
  • 29 + 178907 = 178936
  • 47 + 178889 = 178936
  • 59 + 178877 = 178936
  • 83 + 178853 = 178936
  • 137 + 178799 = 178936
  • 179 + 178757 = 178936

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 178,936 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 178936 first appears in π at position 687,455 of the decimal expansion (the 687,455ordinal-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.
