Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723486, here are decompositions:

  • 3 + 8723483 = 8723486
  • 7 + 8723479 = 8723486
  • 67 + 8723419 = 8723486
  • 127 + 8723359 = 8723486
  • 139 + 8723347 = 8723486
  • 283 + 8723203 = 8723486
  • 337 + 8723149 = 8723486
  • 349 + 8723137 = 8723486

Showing the first eight; more decompositions exist.
