Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613190, here are decompositions:

19 + 31613171 = 31613190
47 + 31613143 = 31613190
53 + 31613137 = 31613190
71 + 31613119 = 31613190
73 + 31613117 = 31613190
83 + 31613107 = 31613190
137 + 31613053 = 31613190
163 + 31613027 = 31613190

Showing the first eight; more decompositions exist.
