Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494152, here are decompositions:

61 + 31494091 = 31494152
73 + 31494079 = 31494152
163 + 31493989 = 31494152
211 + 31493941 = 31494152
271 + 31493881 = 31494152
331 + 31493821 = 31494152
373 + 31493779 = 31494152
409 + 31493743 = 31494152

Showing the first eight; more decompositions exist.
