Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494154, here are decompositions:

11 + 31494143 = 31494154
71 + 31494083 = 31494154
101 + 31494053 = 31494154
113 + 31494041 = 31494154
227 + 31493927 = 31494154
443 + 31493711 = 31494154
641 + 31493513 = 31494154
677 + 31493477 = 31494154

Showing the first eight; more decompositions exist.
