Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722630, here are decompositions:

  • 17 + 8722613 = 8722630
  • 23 + 8722607 = 8722630
  • 89 + 8722541 = 8722630
  • 113 + 8722517 = 8722630
  • 131 + 8722499 = 8722630
  • 239 + 8722391 = 8722630
  • 263 + 8722367 = 8722630
  • 269 + 8722361 = 8722630

Showing the first eight; more decompositions exist.
