Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173786, here are decompositions:

  • 3 + 173783 = 173786
  • 7 + 173779 = 173786
  • 13 + 173773 = 173786
  • 43 + 173743 = 173786
  • 73 + 173713 = 173786
  • 79 + 173707 = 173786
  • 103 + 173683 = 173786
  • 127 + 173659 = 173786

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 173,786 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 173786 first appears in π at position 500,900 of the decimal expansion (the 500,900ordinal-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.
