Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539226, here are decompositions:

83 + 31539143 = 31539226
137 + 31539089 = 31539226
179 + 31539047 = 31539226
239 + 31538987 = 31539226
419 + 31538807 = 31539226
647 + 31538579 = 31539226
1019 + 31538207 = 31539226
1163 + 31538063 = 31539226

Showing the first eight; more decompositions exist.
