Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628700, here are decompositions:

  • 23 + 8628677 = 8628700
  • 53 + 8628647 = 8628700
  • 71 + 8628629 = 8628700
  • 149 + 8628551 = 8628700
  • 251 + 8628449 = 8628700
  • 257 + 8628443 = 8628700
  • 293 + 8628407 = 8628700
  • 317 + 8628383 = 8628700

Showing the first eight; more decompositions exist.
