Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564640, here are decompositions:

  • 23 + 564617 = 564640
  • 47 + 564593 = 564640
  • 107 + 564533 = 564640
  • 149 + 564491 = 564640
  • 173 + 564467 = 564640
  • 191 + 564449 = 564640
  • 233 + 564407 = 564640
  • 239 + 564401 = 564640

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 564,640 and was likely granted around 1895.

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

Position in π

The digit sequence 564640 first appears in π at position 387,760 of the decimal expansion (the 387,760ordinal-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.
