Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625828, here are decompositions:

  • 7 + 8625821 = 8625828
  • 17 + 8625811 = 8625828
  • 19 + 8625809 = 8625828
  • 41 + 8625787 = 8625828
  • 139 + 8625689 = 8625828
  • 179 + 8625649 = 8625828
  • 191 + 8625637 = 8625828
  • 229 + 8625599 = 8625828

Showing the first eight; more decompositions exist.
