Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494192, here are decompositions:

13 + 31494179 = 31494192
31 + 31494161 = 31494192
73 + 31494119 = 31494192
101 + 31494091 = 31494192
109 + 31494083 = 31494192
113 + 31494079 = 31494192
139 + 31494053 = 31494192
151 + 31494041 = 31494192

Showing the first eight; more decompositions exist.
