Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622518, here are decompositions:

  • 7 + 8622511 = 8622518
  • 19 + 8622499 = 8622518
  • 31 + 8622487 = 8622518
  • 97 + 8622421 = 8622518
  • 127 + 8622391 = 8622518
  • 139 + 8622379 = 8622518
  • 181 + 8622337 = 8622518
  • 211 + 8622307 = 8622518

Showing the first eight; more decompositions exist.
