Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503976, here are decompositions:

3 + 31503973 = 31503976
5 + 31503971 = 31503976
47 + 31503929 = 31503976
59 + 31503917 = 31503976
89 + 31503887 = 31503976
113 + 31503863 = 31503976
167 + 31503809 = 31503976
197 + 31503779 = 31503976

Showing the first eight; more decompositions exist.
