Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722258, here are decompositions:

47 + 8722211 = 8722258
71 + 8722187 = 8722258
89 + 8722169 = 8722258
179 + 8722079 = 8722258
239 + 8722019 = 8722258
257 + 8722001 = 8722258
269 + 8721989 = 8722258
317 + 8721941 = 8722258

Showing the first eight; more decompositions exist.
