Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708890, here are decompositions:

  • 41 + 8708849 = 8708890
  • 59 + 8708831 = 8708890
  • 83 + 8708807 = 8708890
  • 149 + 8708741 = 8708890
  • 173 + 8708717 = 8708890
  • 227 + 8708663 = 8708890
  • 233 + 8708657 = 8708890
  • 251 + 8708639 = 8708890

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 8,708,890 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 8708890 first appears in π at position 603,573 of the decimal expansion (the 603,573ordinal-suffix:rd 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.
