Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610244, here are decompositions:

7 + 31610237 = 31610244
13 + 31610231 = 31610244
31 + 31610213 = 31610244
47 + 31610197 = 31610244
73 + 31610171 = 31610244
101 + 31610143 = 31610244
103 + 31610141 = 31610244
131 + 31610113 = 31610244

Showing the first eight; more decompositions exist.
