Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610040, here are decompositions:

17 + 31610023 = 31610040
29 + 31610011 = 31610040
31 + 31610009 = 31610040
47 + 31609993 = 31610040
67 + 31609973 = 31610040
73 + 31609967 = 31610040
83 + 31609957 = 31610040
103 + 31609937 = 31610040

Showing the first eight; more decompositions exist.
