Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494336, here are decompositions:

43 + 31494293 = 31494336
73 + 31494263 = 31494336
79 + 31494257 = 31494336
89 + 31494247 = 31494336
157 + 31494179 = 31494336
179 + 31494157 = 31494336
193 + 31494143 = 31494336
239 + 31494097 = 31494336

Showing the first eight; more decompositions exist.
