Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613274, here are decompositions:

31 + 31613243 = 31613274
47 + 31613227 = 31613274
83 + 31613191 = 31613274
103 + 31613171 = 31613274
131 + 31613143 = 31613274
137 + 31613137 = 31613274
157 + 31613117 = 31613274
167 + 31613107 = 31613274

Showing the first eight; more decompositions exist.
