Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722394, here are decompositions:

3 + 8722391 = 8722394
61 + 8722333 = 8722394
97 + 8722297 = 8722394
103 + 8722291 = 8722394
157 + 8722237 = 8722394
223 + 8722171 = 8722394
271 + 8722123 = 8722394
277 + 8722117 = 8722394

Showing the first eight; more decompositions exist.
