Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494266, here are decompositions:

3 + 31494263 = 31494266
19 + 31494247 = 31494266
109 + 31494157 = 31494266
277 + 31493989 = 31494266
283 + 31493983 = 31494266
367 + 31493899 = 31494266
409 + 31493857 = 31494266
487 + 31493779 = 31494266

Showing the first eight; more decompositions exist.
