Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630638, here are decompositions:

  • 47 + 8630591 = 8630638
  • 251 + 8630387 = 8630638
  • 347 + 8630291 = 8630638
  • 389 + 8630249 = 8630638
  • 431 + 8630207 = 8630638
  • 461 + 8630177 = 8630638
  • 479 + 8630159 = 8630638
  • 521 + 8630117 = 8630638

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 8,630,638 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 8630638 first appears in π at position 254,667 of the decimal expansion (the 254,667ordinal-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.
