Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491126, here are decompositions:

  • 43 + 491083 = 491126
  • 67 + 491059 = 491126
  • 157 + 490969 = 491126
  • 199 + 490927 = 491126
  • 277 + 490849 = 491126
  • 463 + 490663 = 491126
  • 499 + 490627 = 491126
  • 547 + 490579 = 491126

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 491,126 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 491126 first appears in π at position 732,061 of the decimal expansion (the 732,061ordinal-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.
