Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471686, here are decompositions:

  • 3 + 471683 = 471686
  • 13 + 471673 = 471686
  • 37 + 471649 = 471686
  • 67 + 471619 = 471686
  • 79 + 471607 = 471686
  • 97 + 471589 = 471686
  • 199 + 471487 = 471686
  • 283 + 471403 = 471686

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 471,686 and was likely granted around 1891.

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

Position in π

The digit sequence 471686 first appears in π at position 469,185 of the decimal expansion (the 469,185ordinal-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.
