Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513746, here are decompositions:

  • 7 + 513739 = 513746
  • 19 + 513727 = 513746
  • 67 + 513679 = 513746
  • 73 + 513673 = 513746
  • 97 + 513649 = 513746
  • 307 + 513439 = 513746
  • 349 + 513397 = 513746
  • 379 + 513367 = 513746

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 513,746 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 513746 first appears in π at position 512,527 of the decimal expansion (the 512,527ordinal-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.
