Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170854, here are decompositions:

  • 3 + 170851 = 170854
  • 11 + 170843 = 170854
  • 17 + 170837 = 170854
  • 41 + 170813 = 170854
  • 53 + 170801 = 170854
  • 113 + 170741 = 170854
  • 227 + 170627 = 170854
  • 251 + 170603 = 170854

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 170,854 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 170854 first appears in π at position 439,813 of the decimal expansion (the 439,813ordinal-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.
