Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494252, here are decompositions:

5 + 31494247 = 31494252
11 + 31494241 = 31494252
73 + 31494179 = 31494252
109 + 31494143 = 31494252
173 + 31494079 = 31494252
199 + 31494053 = 31494252
211 + 31494041 = 31494252
263 + 31493989 = 31494252

Showing the first eight; more decompositions exist.
