Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550364, here are decompositions:

7 + 31550357 = 31550364
11 + 31550353 = 31550364
37 + 31550327 = 31550364
107 + 31550257 = 31550364
113 + 31550251 = 31550364
151 + 31550213 = 31550364
163 + 31550201 = 31550364
211 + 31550153 = 31550364

Showing the first eight; more decompositions exist.
