Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615248, here are decompositions:

  • 11 + 8615237 = 8615248
  • 17 + 8615231 = 8615248
  • 29 + 8615219 = 8615248
  • 71 + 8615177 = 8615248
  • 149 + 8615099 = 8615248
  • 197 + 8615051 = 8615248
  • 269 + 8614979 = 8615248
  • 281 + 8614967 = 8615248

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 8,615,248 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8615248 first appears in π at position 860,927 of the decimal expansion (the 860,927ordinal-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.
