Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529982, here are decompositions:

5 + 31529977 = 31529982
13 + 31529969 = 31529982
59 + 31529923 = 31529982
83 + 31529899 = 31529982
101 + 31529881 = 31529982
139 + 31529843 = 31529982
163 + 31529819 = 31529982
199 + 31529783 = 31529982

Showing the first eight; more decompositions exist.
