Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728568, here are decompositions:

  • 19 + 8728549 = 8728568
  • 97 + 8728471 = 8728568
  • 181 + 8728387 = 8728568
  • 307 + 8728261 = 8728568
  • 421 + 8728147 = 8728568
  • 439 + 8728129 = 8728568
  • 631 + 8727937 = 8728568
  • 661 + 8727907 = 8728568

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 8,728,568 and was likely granted around 2014.

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

Position in π

The digit sequence 8728568 first appears in π at position 874,504 of the decimal expansion (the 874,504ordinal-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.
