Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610070, here are decompositions:

7 + 31610063 = 31610070
31 + 31610039 = 31610070
47 + 31610023 = 31610070
59 + 31610011 = 31610070
61 + 31610009 = 31610070
97 + 31609973 = 31610070
103 + 31609967 = 31610070
113 + 31609957 = 31610070

Showing the first eight; more decompositions exist.
