Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494104, here are decompositions:

7 + 31494097 = 31494104
13 + 31494091 = 31494104
163 + 31493941 = 31494104
223 + 31493881 = 31494104
283 + 31493821 = 31494104
463 + 31493641 = 31494104
547 + 31493557 = 31494104
571 + 31493533 = 31494104

Showing the first eight; more decompositions exist.
