Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543146, here are decompositions:

13 + 31543133 = 31543146
43 + 31543103 = 31543146
67 + 31543079 = 31543146
79 + 31543067 = 31543146
127 + 31543019 = 31543146
137 + 31543009 = 31543146
179 + 31542967 = 31543146
197 + 31542949 = 31543146

Showing the first eight; more decompositions exist.
