Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543134, here are decompositions:

31 + 31543103 = 31543134
67 + 31543067 = 31543134
163 + 31542971 = 31543134
167 + 31542967 = 31543134
191 + 31542943 = 31543134
193 + 31542941 = 31543134
197 + 31542937 = 31543134
223 + 31542911 = 31543134

Showing the first eight; more decompositions exist.
