Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642064, here are decompositions:

  • 5 + 8642059 = 8642064
  • 7 + 8642057 = 8642064
  • 31 + 8642033 = 8642064
  • 37 + 8642027 = 8642064
  • 61 + 8642003 = 8642064
  • 73 + 8641991 = 8642064
  • 107 + 8641957 = 8642064
  • 173 + 8641891 = 8642064

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 8,642,064 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 8642064 first appears in π at position 714,960 of the decimal expansion (the 714,960ordinal-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.
