Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493294, here are decompositions:

3 + 31493291 = 31493294
43 + 31493251 = 31493294
103 + 31493191 = 31493294
163 + 31493131 = 31493294
211 + 31493083 = 31493294
241 + 31493053 = 31493294
277 + 31493017 = 31493294
331 + 31492963 = 31493294

Showing the first eight; more decompositions exist.
