Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503934, here are decompositions:

3 + 31503931 = 31503934
5 + 31503929 = 31503934
17 + 31503917 = 31503934
23 + 31503911 = 31503934
47 + 31503887 = 31503934
71 + 31503863 = 31503934
491 + 31503443 = 31503934
593 + 31503341 = 31503934

Showing the first eight; more decompositions exist.
