Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503966, here are decompositions:

5 + 31503961 = 31503966
37 + 31503929 = 31503966
79 + 31503887 = 31503966
83 + 31503883 = 31503966
103 + 31503863 = 31503966
113 + 31503853 = 31503966
157 + 31503809 = 31503966
167 + 31503799 = 31503966

Showing the first eight; more decompositions exist.
