Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669040, here are decompositions:

  • 13 + 8669027 = 8669040
  • 47 + 8668993 = 8669040
  • 67 + 8668973 = 8669040
  • 73 + 8668967 = 8669040
  • 89 + 8668951 = 8669040
  • 139 + 8668901 = 8669040
  • 151 + 8668889 = 8669040
  • 167 + 8668873 = 8669040

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 8,669,040 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
