Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522480, here are decompositions:

  • 11 + 522469 = 522480
  • 31 + 522449 = 522480
  • 41 + 522439 = 522480
  • 67 + 522413 = 522480
  • 71 + 522409 = 522480
  • 89 + 522391 = 522480
  • 97 + 522383 = 522480
  • 107 + 522373 = 522480

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 522,480 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 522480 first appears in π at position 147,148 of the decimal expansion (the 147,148ordinal-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.
