Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503950, here are decompositions:

19 + 31503931 = 31503950
67 + 31503883 = 31503950
97 + 31503853 = 31503950
103 + 31503847 = 31503950
109 + 31503841 = 31503950
139 + 31503811 = 31503950
151 + 31503799 = 31503950
199 + 31503751 = 31503950

Showing the first eight; more decompositions exist.
