Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626890, here are decompositions:

  • 29 + 8626861 = 8626890
  • 43 + 8626847 = 8626890
  • 59 + 8626831 = 8626890
  • 67 + 8626823 = 8626890
  • 71 + 8626819 = 8626890
  • 79 + 8626811 = 8626890
  • 89 + 8626801 = 8626890
  • 113 + 8626777 = 8626890

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 8,626,890 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 8626890 first appears in π at position 52,810 of the decimal expansion (the 52,810ordinal-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.
