Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610156, here are decompositions:

13 + 31610143 = 31610156
43 + 31610113 = 31610156
73 + 31610083 = 31610156
163 + 31609993 = 31610156
199 + 31609957 = 31610156
223 + 31609933 = 31610156
307 + 31609849 = 31610156
337 + 31609819 = 31610156

Showing the first eight; more decompositions exist.
