Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494294, here are decompositions:

31 + 31494263 = 31494294
37 + 31494257 = 31494294
47 + 31494247 = 31494294
53 + 31494241 = 31494294
137 + 31494157 = 31494294
151 + 31494143 = 31494294
197 + 31494097 = 31494294
211 + 31494083 = 31494294

Showing the first eight; more decompositions exist.
