Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503954, here are decompositions:

23 + 31503931 = 31503954
37 + 31503917 = 31503954
43 + 31503911 = 31503954
67 + 31503887 = 31503954
71 + 31503883 = 31503954
101 + 31503853 = 31503954
107 + 31503847 = 31503954
113 + 31503841 = 31503954

Showing the first eight; more decompositions exist.
