Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582032, here are decompositions:

5 + 31582027 = 31582032
11 + 31582021 = 31582032
29 + 31582003 = 31582032
59 + 31581973 = 31582032
71 + 31581961 = 31582032
149 + 31581883 = 31582032
151 + 31581881 = 31582032
173 + 31581859 = 31582032

Showing the first eight; more decompositions exist.
