Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550982, here are decompositions:

5 + 31550977 = 31550982
59 + 31550923 = 31550982
61 + 31550921 = 31550982
103 + 31550879 = 31550982
131 + 31550851 = 31550982
149 + 31550833 = 31550982
179 + 31550803 = 31550982
181 + 31550801 = 31550982

Showing the first eight; more decompositions exist.
