Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539366, here are decompositions:

13 + 31539353 = 31539366
17 + 31539349 = 31539366
29 + 31539337 = 31539366
37 + 31539329 = 31539366
83 + 31539283 = 31539366
137 + 31539229 = 31539366
223 + 31539143 = 31539366
277 + 31539089 = 31539366

Showing the first eight; more decompositions exist.
