Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542134, here are decompositions:

31 + 31542103 = 31542134
67 + 31542067 = 31542134
97 + 31542037 = 31542134
103 + 31542031 = 31542134
157 + 31541977 = 31542134
163 + 31541971 = 31542134
241 + 31541893 = 31542134
277 + 31541857 = 31542134

Showing the first eight; more decompositions exist.
