Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722608, here are decompositions:

  • 5 + 8722603 = 8722608
  • 67 + 8722541 = 8722608
  • 109 + 8722499 = 8722608
  • 131 + 8722477 = 8722608
  • 137 + 8722471 = 8722608
  • 149 + 8722459 = 8722608
  • 179 + 8722429 = 8722608
  • 199 + 8722409 = 8722608

Showing the first eight; more decompositions exist.
