Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723568, here are decompositions:

17 + 8723551 = 8723568
37 + 8723531 = 8723568
47 + 8723521 = 8723568
71 + 8723497 = 8723568
89 + 8723479 = 8723568
109 + 8723459 = 8723568
127 + 8723441 = 8723568
131 + 8723437 = 8723568

Showing the first eight; more decompositions exist.
