Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722744, here are decompositions:

5 + 8722739 = 8722744
71 + 8722673 = 8722744
83 + 8722661 = 8722744
101 + 8722643 = 8722744
113 + 8722631 = 8722744
131 + 8722613 = 8722744
137 + 8722607 = 8722744
227 + 8722517 = 8722744

Showing the first eight; more decompositions exist.
