Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621470, here are decompositions:

  • 3 + 8621467 = 8621470
  • 17 + 8621453 = 8621470
  • 41 + 8621429 = 8621470
  • 59 + 8621411 = 8621470
  • 131 + 8621339 = 8621470
  • 227 + 8621243 = 8621470
  • 233 + 8621237 = 8621470
  • 257 + 8621213 = 8621470

Showing the first eight; more decompositions exist.
