Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724212, here are decompositions:

  • 31 + 8724181 = 8724212
  • 43 + 8724169 = 8724212
  • 73 + 8724139 = 8724212
  • 139 + 8724073 = 8724212
  • 199 + 8724013 = 8724212
  • 283 + 8723929 = 8724212
  • 313 + 8723899 = 8724212
  • 379 + 8723833 = 8724212

Showing the first eight; more decompositions exist.
