Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658470, here are decompositions:

  • 157 + 8658313 = 8658470
  • 181 + 8658289 = 8658470
  • 193 + 8658277 = 8658470
  • 277 + 8658193 = 8658470
  • 367 + 8658103 = 8658470
  • 487 + 8657983 = 8658470
  • 547 + 8657923 = 8658470
  • 619 + 8657851 = 8658470

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 8,658,470 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 8658470 first appears in π at position 473,976 of the decimal expansion (the 473,976ordinal-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.
