Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491708, here are decompositions:

  • 31 + 491677 = 491708
  • 97 + 491611 = 491708
  • 127 + 491581 = 491708
  • 181 + 491527 = 491708
  • 211 + 491497 = 491708
  • 331 + 491377 = 491708
  • 337 + 491371 = 491708
  • 367 + 491341 = 491708

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 491,708 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 491708 first appears in π at position 240,548 of the decimal expansion (the 240,548ordinal-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.
