Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590950, here are decompositions:

7 + 31590943 = 31590950
19 + 31590931 = 31590950
43 + 31590907 = 31590950
73 + 31590877 = 31590950
103 + 31590847 = 31590950
109 + 31590841 = 31590950
211 + 31590739 = 31590950
283 + 31590667 = 31590950

Showing the first eight; more decompositions exist.
