Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627380, here are decompositions:

  • 17 + 8627363 = 8627380
  • 23 + 8627357 = 8627380
  • 29 + 8627351 = 8627380
  • 59 + 8627321 = 8627380
  • 137 + 8627243 = 8627380
  • 227 + 8627153 = 8627380
  • 233 + 8627147 = 8627380
  • 239 + 8627141 = 8627380

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 8,627,380 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 8627380 first appears in π at position 368,991 of the decimal expansion (the 368,991ordinal-suffix:st 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.
