Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719858, here are decompositions:

  • 11 + 8719847 = 8719858
  • 41 + 8719817 = 8719858
  • 197 + 8719661 = 8719858
  • 281 + 8719577 = 8719858
  • 317 + 8719541 = 8719858
  • 467 + 8719391 = 8719858
  • 479 + 8719379 = 8719858
  • 491 + 8719367 = 8719858

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 8,719,858 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 8719858 first appears in π at position 946,178 of the decimal expansion (the 946,178ordinal-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.
