Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724010, here are decompositions:

  • 17 + 8723993 = 8724010
  • 23 + 8723987 = 8724010
  • 59 + 8723951 = 8724010
  • 89 + 8723921 = 8724010
  • 101 + 8723909 = 8724010
  • 107 + 8723903 = 8724010
  • 131 + 8723879 = 8724010
  • 401 + 8723609 = 8724010

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 8,724,010 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 8724010 first appears in π at position 622,721 of the decimal expansion (the 622,721ordinal-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.
