Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722488, here are decompositions:

  • 11 + 8722477 = 8722488
  • 17 + 8722471 = 8722488
  • 29 + 8722459 = 8722488
  • 41 + 8722447 = 8722488
  • 59 + 8722429 = 8722488
  • 79 + 8722409 = 8722488
  • 97 + 8722391 = 8722488
  • 127 + 8722361 = 8722488

Showing the first eight; more decompositions exist.
