Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494134, here are decompositions:

37 + 31494097 = 31494134
43 + 31494091 = 31494134
151 + 31493983 = 31494134
193 + 31493941 = 31494134
277 + 31493857 = 31494134
283 + 31493851 = 31494134
313 + 31493821 = 31494134
457 + 31493677 = 31494134

Showing the first eight; more decompositions exist.
