Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520402, here are decompositions:

  • 23 + 520379 = 520402
  • 41 + 520361 = 520402
  • 53 + 520349 = 520402
  • 89 + 520313 = 520402
  • 251 + 520151 = 520402
  • 359 + 520043 = 520402
  • 383 + 520019 = 520402
  • 431 + 519971 = 520402

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 520,402 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 520402 first appears in π at position 729,433 of the decimal expansion (the 729,433ordinal-suffix:rd 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.
