Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503984, here are decompositions:

7 + 31503977 = 31503984
11 + 31503973 = 31503984
13 + 31503971 = 31503984
23 + 31503961 = 31503984
53 + 31503931 = 31503984
67 + 31503917 = 31503984
73 + 31503911 = 31503984
97 + 31503887 = 31503984

Showing the first eight; more decompositions exist.
