Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494006, here are decompositions:

7 + 31493999 = 31494006
17 + 31493989 = 31494006
23 + 31493983 = 31494006
79 + 31493927 = 31494006
97 + 31493909 = 31494006
107 + 31493899 = 31494006
149 + 31493857 = 31494006
223 + 31493783 = 31494006

Showing the first eight; more decompositions exist.
