Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596672, here are decompositions:

11 + 31596661 = 31596672
59 + 31596613 = 31596672
61 + 31596611 = 31596672
89 + 31596583 = 31596672
101 + 31596571 = 31596672
131 + 31596541 = 31596672
199 + 31596473 = 31596672
269 + 31596403 = 31596672

Showing the first eight; more decompositions exist.
