Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494086, here are decompositions:

3 + 31494083 = 31494086
7 + 31494079 = 31494086
97 + 31493989 = 31494086
103 + 31493983 = 31494086
229 + 31493857 = 31494086
307 + 31493779 = 31494086
397 + 31493689 = 31494086
409 + 31493677 = 31494086

Showing the first eight; more decompositions exist.
