Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494062, here are decompositions:

73 + 31493989 = 31494062
79 + 31493983 = 31494062
163 + 31493899 = 31494062
181 + 31493881 = 31494062
211 + 31493851 = 31494062
241 + 31493821 = 31494062
283 + 31493779 = 31494062
373 + 31493689 = 31494062

Showing the first eight; more decompositions exist.
