Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722396, here are decompositions:

3 + 8722393 = 8722396
5 + 8722391 = 8722396
29 + 8722367 = 8722396
113 + 8722283 = 8722396
173 + 8722223 = 8722396
227 + 8722169 = 8722396
317 + 8722079 = 8722396
467 + 8721929 = 8722396

Showing the first eight; more decompositions exist.
