Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491160, here are decompositions:

  • 11 + 491149 = 491160
  • 23 + 491137 = 491160
  • 31 + 491129 = 491160
  • 79 + 491081 = 491160
  • 101 + 491059 = 491160
  • 157 + 491003 = 491160
  • 167 + 490993 = 491160
  • 191 + 490969 = 491160

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 491,160 and was likely granted around 1892.

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

Position in π

The digit sequence 491160 first appears in π at position 906,433 of the decimal expansion (the 906,433ordinal-suffix:rd 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.
