Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503968, here are decompositions:

7 + 31503961 = 31503968
37 + 31503931 = 31503968
127 + 31503841 = 31503968
157 + 31503811 = 31503968
241 + 31503727 = 31503968
337 + 31503631 = 31503968
409 + 31503559 = 31503968
439 + 31503529 = 31503968

Showing the first eight; more decompositions exist.
