Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494050, here are decompositions:

61 + 31493989 = 31494050
67 + 31493983 = 31494050
109 + 31493941 = 31494050
151 + 31493899 = 31494050
193 + 31493857 = 31494050
199 + 31493851 = 31494050
229 + 31493821 = 31494050
271 + 31493779 = 31494050

Showing the first eight; more decompositions exist.
