Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513438, here are decompositions:

  • 7 + 513431 = 513438
  • 11 + 513427 = 513438
  • 19 + 513419 = 513438
  • 31 + 513407 = 513438
  • 41 + 513397 = 513438
  • 67 + 513371 = 513438
  • 71 + 513367 = 513438
  • 97 + 513341 = 513438

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 513,438 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 513438 first appears in π at position 264,545 of the decimal expansion (the 264,545ordinal-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.
