Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722764, here are decompositions:

7 + 8722757 = 8722764
53 + 8722711 = 8722764
103 + 8722661 = 8722764
151 + 8722613 = 8722764
157 + 8722607 = 8722764
223 + 8722541 = 8722764
293 + 8722471 = 8722764
317 + 8722447 = 8722764

Showing the first eight; more decompositions exist.
