Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516824, here are decompositions:

5 + 31516819 = 31516824
13 + 31516811 = 31516824
37 + 31516787 = 31516824
43 + 31516781 = 31516824
47 + 31516777 = 31516824
67 + 31516757 = 31516824
71 + 31516753 = 31516824
127 + 31516697 = 31516824

Showing the first eight; more decompositions exist.
