Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482816, here are decompositions:

17 + 31482799 = 31482816
37 + 31482779 = 31482816
73 + 31482743 = 31482816
107 + 31482709 = 31482816
109 + 31482707 = 31482816
149 + 31482667 = 31482816
173 + 31482643 = 31482816
199 + 31482617 = 31482816

Showing the first eight; more decompositions exist.
