Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491012, here are decompositions:

  • 19 + 490993 = 491012
  • 43 + 490969 = 491012
  • 61 + 490951 = 491012
  • 163 + 490849 = 491012
  • 229 + 490783 = 491012
  • 241 + 490771 = 491012
  • 271 + 490741 = 491012
  • 349 + 490663 = 491012

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 491,012 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 491012 first appears in π at position 422,586 of the decimal expansion (the 422,586ordinal-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.
