Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629478, here are decompositions:

  • 31 + 8629447 = 8629478
  • 37 + 8629441 = 8629478
  • 181 + 8629297 = 8629478
  • 199 + 8629279 = 8629478
  • 307 + 8629171 = 8629478
  • 337 + 8629141 = 8629478
  • 541 + 8628937 = 8629478
  • 619 + 8628859 = 8629478

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 8,629,478 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 8629478 first appears in π at position 494,210 of the decimal expansion (the 494,210ordinal-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.
