Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722618, here are decompositions:

5 + 8722613 = 8722618
11 + 8722607 = 8722618
101 + 8722517 = 8722618
227 + 8722391 = 8722618
251 + 8722367 = 8722618
257 + 8722361 = 8722618
431 + 8722187 = 8722618
449 + 8722169 = 8722618

Showing the first eight; more decompositions exist.
