Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630490, here are decompositions:

  • 7 + 8630483 = 8630490
  • 13 + 8630477 = 8630490
  • 41 + 8630449 = 8630490
  • 47 + 8630443 = 8630490
  • 73 + 8630417 = 8630490
  • 103 + 8630387 = 8630490
  • 179 + 8630311 = 8630490
  • 199 + 8630291 = 8630490

Showing the first eight; more decompositions exist.
