Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520408, here are decompositions:

  • 29 + 520379 = 520408
  • 47 + 520361 = 520408
  • 59 + 520349 = 520408
  • 101 + 520307 = 520408
  • 167 + 520241 = 520408
  • 257 + 520151 = 520408
  • 389 + 520019 = 520408
  • 419 + 519989 = 520408

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 520,408 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 520408 first appears in π at position 124,761 of the decimal expansion (the 124,761ordinal-suffix:st 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.
