Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617252, here are decompositions:

13 + 31617239 = 31617252
53 + 31617199 = 31617252
71 + 31617181 = 31617252
103 + 31617149 = 31617252
151 + 31617101 = 31617252
179 + 31617073 = 31617252
223 + 31617029 = 31617252
229 + 31617023 = 31617252

Showing the first eight; more decompositions exist.
