Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722246, here are decompositions:

23 + 8722223 = 8722246
53 + 8722193 = 8722246
59 + 8722187 = 8722246
149 + 8722097 = 8722246
167 + 8722079 = 8722246
227 + 8722019 = 8722246
257 + 8721989 = 8722246
317 + 8721929 = 8722246

Showing the first eight; more decompositions exist.
