Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503964, here are decompositions:

3 + 31503961 = 31503964
47 + 31503917 = 31503964
53 + 31503911 = 31503964
101 + 31503863 = 31503964
251 + 31503713 = 31503964
521 + 31503443 = 31503964
641 + 31503323 = 31503964
761 + 31503203 = 31503964

Showing the first eight; more decompositions exist.
