Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613244, here are decompositions:

17 + 31613227 = 31613244
53 + 31613191 = 31613244
73 + 31613171 = 31613244
101 + 31613143 = 31613244
107 + 31613137 = 31613244
127 + 31613117 = 31613244
137 + 31613107 = 31613244
191 + 31613053 = 31613244

Showing the first eight; more decompositions exist.
