Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729888, here are decompositions:

  • 7 + 8729881 = 8729888
  • 19 + 8729869 = 8729888
  • 67 + 8729821 = 8729888
  • 199 + 8729689 = 8729888
  • 229 + 8729659 = 8729888
  • 241 + 8729647 = 8729888
  • 331 + 8729557 = 8729888
  • 397 + 8729491 = 8729888

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 8,729,888 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 8729888 first appears in π at position 424,054 of the decimal expansion (the 424,054ordinal-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.
