Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723616, here are decompositions:

  • 7 + 8723609 = 8723616
  • 23 + 8723593 = 8723616
  • 47 + 8723569 = 8723616
  • 137 + 8723479 = 8723616
  • 157 + 8723459 = 8723616
  • 179 + 8723437 = 8723616
  • 193 + 8723423 = 8723616
  • 197 + 8723419 = 8723616

Showing the first eight; more decompositions exist.
