Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624538, here are decompositions:

  • 31 + 8624507 = 8624538
  • 61 + 8624477 = 8624538
  • 79 + 8624459 = 8624538
  • 89 + 8624449 = 8624538
  • 211 + 8624327 = 8624538
  • 227 + 8624311 = 8624538
  • 271 + 8624267 = 8624538
  • 317 + 8624221 = 8624538

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 8,624,538 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 8624538 first appears in π at position 774,164 of the decimal expansion (the 774,164ordinal-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.
