Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494366, here are decompositions:

19 + 31494347 = 31494366
73 + 31494293 = 31494366
103 + 31494263 = 31494366
109 + 31494257 = 31494366
223 + 31494143 = 31494366
269 + 31494097 = 31494366
283 + 31494083 = 31494366
313 + 31494053 = 31494366

Showing the first eight; more decompositions exist.
