Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629972, here are decompositions:

  • 11 + 8629961 = 8629972
  • 23 + 8629949 = 8629972
  • 83 + 8629889 = 8629972
  • 89 + 8629883 = 8629972
  • 149 + 8629823 = 8629972
  • 233 + 8629739 = 8629972
  • 293 + 8629679 = 8629972
  • 311 + 8629661 = 8629972

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 8,629,972 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 8629972 first appears in π at position 470,761 of the decimal expansion (the 470,761ordinal-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.
