Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539294, here are decompositions:

5 + 31539289 = 31539294
11 + 31539283 = 31539294
23 + 31539271 = 31539294
53 + 31539241 = 31539294
103 + 31539191 = 31539294
131 + 31539163 = 31539294
151 + 31539143 = 31539294
211 + 31539083 = 31539294

Showing the first eight; more decompositions exist.
