Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494132, here are decompositions:

13 + 31494119 = 31494132
41 + 31494091 = 31494132
53 + 31494079 = 31494132
79 + 31494053 = 31494132
149 + 31493983 = 31494132
181 + 31493951 = 31494132
191 + 31493941 = 31494132
223 + 31493909 = 31494132

Showing the first eight; more decompositions exist.
