Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491672, here are decompositions:

  • 3 + 491669 = 491672
  • 19 + 491653 = 491672
  • 61 + 491611 = 491672
  • 79 + 491593 = 491672
  • 211 + 491461 = 491672
  • 331 + 491341 = 491672
  • 373 + 491299 = 491672
  • 421 + 491251 = 491672

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 491,672 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 491672 first appears in π at position 710,388 of the decimal expansion (the 710,388ordinal-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.
