Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610004, here are decompositions:

11 + 31609993 = 31610004
31 + 31609973 = 31610004
37 + 31609967 = 31610004
47 + 31609957 = 31610004
67 + 31609937 = 31610004
71 + 31609933 = 31610004
73 + 31609931 = 31610004
157 + 31609847 = 31610004

Showing the first eight; more decompositions exist.
