Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494092, here are decompositions:

13 + 31494079 = 31494092
103 + 31493989 = 31494092
109 + 31493983 = 31494092
151 + 31493941 = 31494092
193 + 31493899 = 31494092
211 + 31493881 = 31494092
241 + 31493851 = 31494092
271 + 31493821 = 31494092

Showing the first eight; more decompositions exist.
