Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722760, here are decompositions:

  • 3 + 8722757 = 8722760
  • 139 + 8722621 = 8722760
  • 157 + 8722603 = 8722760
  • 283 + 8722477 = 8722760
  • 313 + 8722447 = 8722760
  • 331 + 8722429 = 8722760
  • 337 + 8722423 = 8722760
  • 367 + 8722393 = 8722760

Showing the first eight; more decompositions exist.
