Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613154, here are decompositions:

11 + 31613143 = 31613154
17 + 31613137 = 31613154
37 + 31613117 = 31613154
47 + 31613107 = 31613154
101 + 31613053 = 31613154
127 + 31613027 = 31613154
163 + 31612991 = 31613154
173 + 31612981 = 31613154

Showing the first eight; more decompositions exist.
