Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501668, here are decompositions:

  • 31 + 501637 = 501668
  • 67 + 501601 = 501668
  • 157 + 501511 = 501668
  • 241 + 501427 = 501668
  • 397 + 501271 = 501668
  • 439 + 501229 = 501668
  • 547 + 501121 = 501668
  • 631 + 501037 = 501668

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 501,668 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 501668 first appears in π at position 296,049 of the decimal expansion (the 296,049ordinal-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.
