Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550196, here are decompositions:

17 + 31550179 = 31550196
19 + 31550177 = 31550196
43 + 31550153 = 31550196
47 + 31550149 = 31550196
59 + 31550137 = 31550196
89 + 31550107 = 31550196
103 + 31550093 = 31550196
149 + 31550047 = 31550196

Showing the first eight; more decompositions exist.
