Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722672, here are decompositions:

11 + 8722661 = 8722672
29 + 8722643 = 8722672
41 + 8722631 = 8722672
59 + 8722613 = 8722672
131 + 8722541 = 8722672
173 + 8722499 = 8722672
263 + 8722409 = 8722672
281 + 8722391 = 8722672

Showing the first eight; more decompositions exist.
