Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494124, here are decompositions:

5 + 31494119 = 31494124
41 + 31494083 = 31494124
71 + 31494053 = 31494124
83 + 31494041 = 31494124
173 + 31493951 = 31494124
197 + 31493927 = 31494124
647 + 31493477 = 31494124
677 + 31493447 = 31494124

Showing the first eight; more decompositions exist.
