Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617222, here are decompositions:

23 + 31617199 = 31617222
41 + 31617181 = 31617222
73 + 31617149 = 31617222
89 + 31617133 = 31617222
149 + 31617073 = 31617222
173 + 31617049 = 31617222
193 + 31617029 = 31617222
199 + 31617023 = 31617222

Showing the first eight; more decompositions exist.
