Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723090, here are decompositions:

  • 37 + 8723053 = 8723090
  • 43 + 8723047 = 8723090
  • 73 + 8723017 = 8723090
  • 97 + 8722993 = 8723090
  • 109 + 8722981 = 8723090
  • 199 + 8722891 = 8723090
  • 379 + 8722711 = 8723090
  • 487 + 8722603 = 8723090

Showing the first eight; more decompositions exist.
