Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491066, here are decompositions:

  • 7 + 491059 = 491066
  • 73 + 490993 = 491066
  • 97 + 490969 = 491066
  • 109 + 490957 = 491066
  • 139 + 490927 = 491066
  • 229 + 490837 = 491066
  • 283 + 490783 = 491066
  • 439 + 490627 = 491066

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 491,066 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 491066 first appears in π at position 554,881 of the decimal expansion (the 554,881ordinal-suffix:st 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.
