Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539246, here are decompositions:

5 + 31539241 = 31539246
17 + 31539229 = 31539246
83 + 31539163 = 31539246
103 + 31539143 = 31539246
157 + 31539089 = 31539246
163 + 31539083 = 31539246
173 + 31539073 = 31539246
199 + 31539047 = 31539246

Showing the first eight; more decompositions exist.
