Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758220, here are decompositions:

  • 19 + 8758201 = 8758220
  • 103 + 8758117 = 8758220
  • 127 + 8758093 = 8758220
  • 139 + 8758081 = 8758220
  • 277 + 8757943 = 8758220
  • 421 + 8757799 = 8758220
  • 463 + 8757757 = 8758220
  • 577 + 8757643 = 8758220

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 8,758,220 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 8758220 first appears in π at position 933,920 of the decimal expansion (the 933,920ordinal-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.
