Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491832, here are decompositions:

  • 13 + 491819 = 491832
  • 43 + 491789 = 491832
  • 59 + 491773 = 491832
  • 101 + 491731 = 491832
  • 113 + 491719 = 491832
  • 163 + 491669 = 491832
  • 179 + 491653 = 491832
  • 181 + 491651 = 491832

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 491,832 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 491832 first appears in π at position 572,593 of the decimal expansion (the 572,593ordinal-suffix:rd 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.
