Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622780, here are decompositions:

  • 13 + 8622767 = 8622780
  • 17 + 8622763 = 8622780
  • 59 + 8622721 = 8622780
  • 73 + 8622707 = 8622780
  • 97 + 8622683 = 8622780
  • 251 + 8622529 = 8622780
  • 269 + 8622511 = 8622780
  • 281 + 8622499 = 8622780

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 8,622,780 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 8622780 first appears in π at position 146,619 of the decimal expansion (the 146,619ordinal-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.
