Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610042, here are decompositions:

3 + 31610039 = 31610042
19 + 31610023 = 31610042
31 + 31610011 = 31610042
109 + 31609933 = 31610042
181 + 31609861 = 31610042
193 + 31609849 = 31610042
223 + 31609819 = 31610042
229 + 31609813 = 31610042

Showing the first eight; more decompositions exist.
