Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179856, here are decompositions:

  • 7 + 179849 = 179856
  • 23 + 179833 = 179856
  • 29 + 179827 = 179856
  • 37 + 179819 = 179856
  • 43 + 179813 = 179856
  • 107 + 179749 = 179856
  • 113 + 179743 = 179856
  • 137 + 179719 = 179856

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 179,856 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 179856 first appears in π at position 192,864 of the decimal expansion (the 192,864ordinal-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.
