Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465640, here are decompositions:

  • 29 + 465611 = 465640
  • 53 + 465587 = 465640
  • 59 + 465581 = 465640
  • 89 + 465551 = 465640
  • 233 + 465407 = 465640
  • 257 + 465383 = 465640
  • 347 + 465293 = 465640
  • 359 + 465281 = 465640

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 465,640 and was likely granted around 1891.

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

Position in π

The digit sequence 465640 first appears in π at position 459,792 of the decimal expansion (the 459,792ordinal-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.
