Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491118, here are decompositions:

  • 37 + 491081 = 491118
  • 59 + 491059 = 491118
  • 79 + 491039 = 491118
  • 127 + 490991 = 491118
  • 149 + 490969 = 491118
  • 151 + 490967 = 491118
  • 167 + 490951 = 491118
  • 181 + 490937 = 491118

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 491,118 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 491118 first appears in π at position 338,620 of the decimal expansion (the 338,620ordinal-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.
