Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513626, here are decompositions:

  • 97 + 513529 = 513626
  • 199 + 513427 = 513626
  • 229 + 513397 = 513626
  • 307 + 513319 = 513626
  • 313 + 513313 = 513626
  • 349 + 513277 = 513626
  • 457 + 513169 = 513626
  • 523 + 513103 = 513626

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 513,626 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 513626 first appears in π at position 266,066 of the decimal expansion (the 266,066ordinal-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.
