Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173808, here are decompositions:

  • 29 + 173779 = 173808
  • 31 + 173777 = 173808
  • 67 + 173741 = 173808
  • 79 + 173729 = 173808
  • 101 + 173707 = 173808
  • 109 + 173699 = 173808
  • 137 + 173671 = 173808
  • 139 + 173669 = 173808

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 173,808 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 173808 first appears in π at position 864,027 of the decimal expansion (the 864,027ordinal-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.
