Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480966, here are decompositions:

3 + 31480963 = 31480966
17 + 31480949 = 31480966
47 + 31480919 = 31480966
53 + 31480913 = 31480966
137 + 31480829 = 31480966
173 + 31480793 = 31480966
197 + 31480769 = 31480966
233 + 31480733 = 31480966

Showing the first eight; more decompositions exist.
