Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620028, here are decompositions:

  • 31 + 8619997 = 8620028
  • 211 + 8619817 = 8620028
  • 367 + 8619661 = 8620028
  • 379 + 8619649 = 8620028
  • 601 + 8619427 = 8620028
  • 607 + 8619421 = 8620028
  • 631 + 8619397 = 8620028
  • 787 + 8619241 = 8620028

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 8,620,028 and was likely granted around 2013.

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

Position in π

The digit sequence 8620028 first appears in π at position 274,614 of the decimal expansion (the 274,614ordinal-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.
