Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494364, here are decompositions:

17 + 31494347 = 31494364
71 + 31494293 = 31494364
101 + 31494263 = 31494364
107 + 31494257 = 31494364
281 + 31494083 = 31494364
311 + 31494053 = 31494364
647 + 31493717 = 31494364
653 + 31493711 = 31494364

Showing the first eight; more decompositions exist.
