Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550232, here are decompositions:

11 + 31550221 = 31550232
19 + 31550213 = 31550232
31 + 31550201 = 31550232
53 + 31550179 = 31550232
79 + 31550153 = 31550232
83 + 31550149 = 31550232
101 + 31550131 = 31550232
113 + 31550119 = 31550232

Showing the first eight; more decompositions exist.
