Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491498, here are decompositions:

  • 37 + 491461 = 491498
  • 127 + 491371 = 491498
  • 157 + 491341 = 491498
  • 199 + 491299 = 491498
  • 331 + 491167 = 491498
  • 349 + 491149 = 491498
  • 439 + 491059 = 491498
  • 457 + 491041 = 491498

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 491,498 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 491498 first appears in π at position 386,372 of the decimal expansion (the 386,372ordinal-suffix:nd 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.
