Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617264, here are decompositions:

11 + 31617253 = 31617264
13 + 31617251 = 31617264
83 + 31617181 = 31617264
97 + 31617167 = 31617264
131 + 31617133 = 31617264
163 + 31617101 = 31617264
191 + 31617073 = 31617264
241 + 31617023 = 31617264

Showing the first eight; more decompositions exist.
