Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723518, here are decompositions:

59 + 8723459 = 8723518
131 + 8723387 = 8723518
197 + 8723321 = 8723518
569 + 8722949 = 8723518
641 + 8722877 = 8723518
659 + 8722859 = 8723518
677 + 8722841 = 8723518
719 + 8722799 = 8723518

Showing the first eight; more decompositions exist.
