Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491846, here are decompositions:

  • 13 + 491833 = 491846
  • 73 + 491773 = 491846
  • 109 + 491737 = 491846
  • 127 + 491719 = 491846
  • 139 + 491707 = 491846
  • 193 + 491653 = 491846
  • 307 + 491539 = 491846
  • 349 + 491497 = 491846

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 491,846 and was likely granted around 1893.

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

Position in π

The digit sequence 491846 first appears in π at position 190,471 of the decimal expansion (the 190,471ordinal-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.
