Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647384, here are decompositions:

  • 17 + 8647367 = 8647384
  • 107 + 8647277 = 8647384
  • 131 + 8647253 = 8647384
  • 191 + 8647193 = 8647384
  • 227 + 8647157 = 8647384
  • 257 + 8647127 = 8647384
  • 293 + 8647091 = 8647384
  • 353 + 8647031 = 8647384

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 8,647,384 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 8647384 first appears in π at position 927,900 of the decimal expansion (the 927,900ordinal-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.
