Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494098, here are decompositions:

7 + 31494091 = 31494098
19 + 31494079 = 31494098
109 + 31493989 = 31494098
157 + 31493941 = 31494098
199 + 31493899 = 31494098
241 + 31493857 = 31494098
277 + 31493821 = 31494098
409 + 31493689 = 31494098

Showing the first eight; more decompositions exist.
