Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550946, here are decompositions:

23 + 31550923 = 31550946
67 + 31550879 = 31550946
79 + 31550867 = 31550946
109 + 31550837 = 31550946
113 + 31550833 = 31550946
139 + 31550807 = 31550946
149 + 31550797 = 31550946
199 + 31550747 = 31550946

Showing the first eight; more decompositions exist.
