Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550214, here are decompositions:

13 + 31550201 = 31550214
37 + 31550177 = 31550214
61 + 31550153 = 31550214
83 + 31550131 = 31550214
103 + 31550111 = 31550214
107 + 31550107 = 31550214
151 + 31550063 = 31550214
167 + 31550047 = 31550214

Showing the first eight; more decompositions exist.
