Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628130, here are decompositions:

  • 23 + 8628107 = 8628130
  • 53 + 8628077 = 8628130
  • 113 + 8628017 = 8628130
  • 191 + 8627939 = 8628130
  • 227 + 8627903 = 8628130
  • 233 + 8627897 = 8628130
  • 263 + 8627867 = 8628130
  • 317 + 8627813 = 8628130

Showing the first eight; more decompositions exist.
