Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723450, here are decompositions:

  • 13 + 8723437 = 8723450
  • 31 + 8723419 = 8723450
  • 97 + 8723353 = 8723450
  • 103 + 8723347 = 8723450
  • 139 + 8723311 = 8723450
  • 313 + 8723137 = 8723450
  • 397 + 8723053 = 8723450
  • 409 + 8723041 = 8723450

Showing the first eight; more decompositions exist.
