Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503948, here are decompositions:

17 + 31503931 = 31503948
19 + 31503929 = 31503948
31 + 31503917 = 31503948
37 + 31503911 = 31503948
61 + 31503887 = 31503948
101 + 31503847 = 31503948
107 + 31503841 = 31503948
137 + 31503811 = 31503948

Showing the first eight; more decompositions exist.
