Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628430, here are decompositions:

  • 23 + 8628407 = 8628430
  • 47 + 8628383 = 8628430
  • 53 + 8628377 = 8628430
  • 71 + 8628359 = 8628430
  • 137 + 8628293 = 8628430
  • 197 + 8628233 = 8628430
  • 227 + 8628203 = 8628430
  • 257 + 8628173 = 8628430

Showing the first eight; more decompositions exist.
