Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550954, here are decompositions:

7 + 31550947 = 31550954
31 + 31550923 = 31550954
103 + 31550851 = 31550954
151 + 31550803 = 31550954
157 + 31550797 = 31550954
163 + 31550791 = 31550954
223 + 31550731 = 31550954
283 + 31550671 = 31550954

Showing the first eight; more decompositions exist.
