Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494112, here are decompositions:

29 + 31494083 = 31494112
59 + 31494053 = 31494112
71 + 31494041 = 31494112
113 + 31493999 = 31494112
401 + 31493711 = 31494112
593 + 31493519 = 31494112
599 + 31493513 = 31494112
773 + 31493339 = 31494112

Showing the first eight; more decompositions exist.
