Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702790, here are decompositions:

  • 13 + 8702777 = 8702790
  • 37 + 8702753 = 8702790
  • 43 + 8702747 = 8702790
  • 59 + 8702731 = 8702790
  • 97 + 8702693 = 8702790
  • 101 + 8702689 = 8702790
  • 127 + 8702663 = 8702790
  • 193 + 8702597 = 8702790

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 8,702,790 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 8702790 first appears in π at position 5,467 of the decimal expansion (the 5,467ordinal-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.
