Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610064, here are decompositions:

41 + 31610023 = 31610064
53 + 31610011 = 31610064
71 + 31609993 = 31610064
97 + 31609967 = 31610064
107 + 31609957 = 31610064
127 + 31609937 = 31610064
131 + 31609933 = 31610064
181 + 31609883 = 31610064

Showing the first eight; more decompositions exist.
