Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494002, here are decompositions:

3 + 31493999 = 31494002
13 + 31493989 = 31494002
19 + 31493983 = 31494002
61 + 31493941 = 31494002
103 + 31493899 = 31494002
151 + 31493851 = 31494002
181 + 31493821 = 31494002
223 + 31493779 = 31494002

Showing the first eight; more decompositions exist.
