Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494108, here are decompositions:

11 + 31494097 = 31494108
17 + 31494091 = 31494108
29 + 31494079 = 31494108
67 + 31494041 = 31494108
109 + 31493999 = 31494108
157 + 31493951 = 31494108
167 + 31493941 = 31494108
181 + 31493927 = 31494108

Showing the first eight; more decompositions exist.
