Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722716, here are decompositions:

5 + 8722711 = 8722716
43 + 8722673 = 8722716
73 + 8722643 = 8722716
103 + 8722613 = 8722716
109 + 8722607 = 8722716
113 + 8722603 = 8722716
199 + 8722517 = 8722716
239 + 8722477 = 8722716

Showing the first eight; more decompositions exist.
