Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722648, here are decompositions:

5 + 8722643 = 8722648
17 + 8722631 = 8722648
41 + 8722607 = 8722648
107 + 8722541 = 8722648
131 + 8722517 = 8722648
149 + 8722499 = 8722648
239 + 8722409 = 8722648
257 + 8722391 = 8722648

Showing the first eight; more decompositions exist.
