Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722252, here are decompositions:

29 + 8722223 = 8722252
41 + 8722211 = 8722252
59 + 8722193 = 8722252
83 + 8722169 = 8722252
173 + 8722079 = 8722252
233 + 8722019 = 8722252
251 + 8722001 = 8722252
263 + 8721989 = 8722252

Showing the first eight; more decompositions exist.
