Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494102, here are decompositions:

5 + 31494097 = 31494102
11 + 31494091 = 31494102
19 + 31494083 = 31494102
23 + 31494079 = 31494102
61 + 31494041 = 31494102
103 + 31493999 = 31494102
113 + 31493989 = 31494102
151 + 31493951 = 31494102

Showing the first eight; more decompositions exist.
