Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610046, here are decompositions:

7 + 31610039 = 31610046
23 + 31610023 = 31610046
37 + 31610009 = 31610046
53 + 31609993 = 31610046
73 + 31609973 = 31610046
79 + 31609967 = 31610046
89 + 31609957 = 31610046
109 + 31609937 = 31610046

Showing the first eight; more decompositions exist.
