Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722684, here are decompositions:

11 + 8722673 = 8722684
23 + 8722661 = 8722684
41 + 8722643 = 8722684
53 + 8722631 = 8722684
71 + 8722613 = 8722684
167 + 8722517 = 8722684
293 + 8722391 = 8722684
317 + 8722367 = 8722684

Showing the first eight; more decompositions exist.
