Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512646, here are decompositions:

  • 5 + 512641 = 512646
  • 37 + 512609 = 512646
  • 53 + 512593 = 512646
  • 67 + 512579 = 512646
  • 73 + 512573 = 512646
  • 103 + 512543 = 512646
  • 109 + 512537 = 512646
  • 139 + 512507 = 512646

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 512,646 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 512646 first appears in π at position 441,950 of the decimal expansion (the 441,950ordinal-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.
