Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516792, here are decompositions:

3 + 31516789 = 31516792
5 + 31516787 = 31516792
11 + 31516781 = 31516792
89 + 31516703 = 31516792
173 + 31516619 = 31516792
179 + 31516613 = 31516792
233 + 31516559 = 31516792
269 + 31516523 = 31516792

Showing the first eight; more decompositions exist.
