Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610010, here are decompositions:

17 + 31609993 = 31610010
37 + 31609973 = 31610010
43 + 31609967 = 31610010
53 + 31609957 = 31610010
73 + 31609937 = 31610010
79 + 31609931 = 31610010
127 + 31609883 = 31610010
139 + 31609871 = 31610010

Showing the first eight; more decompositions exist.
