Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704478, here are decompositions:

  • 61 + 8704417 = 8704478
  • 109 + 8704369 = 8704478
  • 127 + 8704351 = 8704478
  • 199 + 8704279 = 8704478
  • 619 + 8703859 = 8704478
  • 661 + 8703817 = 8704478
  • 691 + 8703787 = 8704478
  • 859 + 8703619 = 8704478

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 8,704,478 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 8704478 first appears in π at position 248,041 of the decimal expansion (the 248,041ordinal-suffix:st 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.
