Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723188, here are decompositions:

  • 107 + 8723081 = 8723188
  • 197 + 8722991 = 8723188
  • 239 + 8722949 = 8723188
  • 311 + 8722877 = 8723188
  • 347 + 8722841 = 8723188
  • 359 + 8722829 = 8723188
  • 389 + 8722799 = 8723188
  • 431 + 8722757 = 8723188

Showing the first eight; more decompositions exist.
