Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494110, here are decompositions:

13 + 31494097 = 31494110
19 + 31494091 = 31494110
31 + 31494079 = 31494110
127 + 31493983 = 31494110
211 + 31493899 = 31494110
229 + 31493881 = 31494110
331 + 31493779 = 31494110
367 + 31493743 = 31494110

Showing the first eight; more decompositions exist.
