Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522724, here are decompositions:

  • 5 + 522719 = 522724
  • 17 + 522707 = 522724
  • 47 + 522677 = 522724
  • 101 + 522623 = 522724
  • 227 + 522497 = 522724
  • 311 + 522413 = 522724
  • 353 + 522371 = 522724
  • 401 + 522323 = 522724

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 522,724 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 522724 first appears in π at position 588,172 of the decimal expansion (the 588,172ordinal-suffix:nd 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.
