Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610144, here are decompositions:

3 + 31610141 = 31610144
31 + 31610113 = 31610144
37 + 31610107 = 31610144
61 + 31610083 = 31610144
151 + 31609993 = 31610144
211 + 31609933 = 31610144
283 + 31609861 = 31610144
331 + 31609813 = 31610144

Showing the first eight; more decompositions exist.
