Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606950, here are decompositions:

7 + 31606943 = 31606950
19 + 31606931 = 31606950
31 + 31606919 = 31606950
47 + 31606903 = 31606950
71 + 31606879 = 31606950
103 + 31606847 = 31606950
139 + 31606811 = 31606950
197 + 31606753 = 31606950

Showing the first eight; more decompositions exist.
