Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723608, here are decompositions:

149 + 8723459 = 8723608
167 + 8723441 = 8723608
617 + 8722991 = 8723608
659 + 8722949 = 8723608
809 + 8722799 = 8723608
947 + 8722661 = 8723608
977 + 8722631 = 8723608
1091 + 8722517 = 8723608

Showing the first eight; more decompositions exist.
