Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722430, here are decompositions:

  • 7 + 8722423 = 8722430
  • 37 + 8722393 = 8722430
  • 97 + 8722333 = 8722430
  • 127 + 8722303 = 8722430
  • 139 + 8722291 = 8722430
  • 193 + 8722237 = 8722430
  • 307 + 8722123 = 8722430
  • 313 + 8722117 = 8722430

Showing the first eight; more decompositions exist.
