Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513802, here are decompositions:

  • 41 + 513761 = 513802
  • 53 + 513749 = 513802
  • 71 + 513731 = 513802
  • 83 + 513719 = 513802
  • 269 + 513533 = 513802
  • 293 + 513509 = 513802
  • 383 + 513419 = 513802
  • 431 + 513371 = 513802

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 513,802 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 513802 first appears in π at position 967,076 of the decimal expansion (the 967,076ordinal-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.
