Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610084, here are decompositions:

3 + 31610081 = 31610084
61 + 31610023 = 31610084
73 + 31610011 = 31610084
127 + 31609957 = 31610084
151 + 31609933 = 31610084
223 + 31609861 = 31610084
271 + 31609813 = 31610084
307 + 31609777 = 31610084

Showing the first eight; more decompositions exist.
