Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520404, here are decompositions:

  • 11 + 520393 = 520404
  • 23 + 520381 = 520404
  • 41 + 520363 = 520404
  • 43 + 520361 = 520404
  • 47 + 520357 = 520404
  • 97 + 520307 = 520404
  • 107 + 520297 = 520404
  • 113 + 520291 = 520404

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 520,404 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 520404 first appears in π at position 164,610 of the decimal expansion (the 164,610ordinal-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.
