Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610944, here are decompositions:

173 + 31610771 = 31610944
383 + 31610561 = 31610944
653 + 31610291 = 31610944
773 + 31610171 = 31610944
863 + 31610081 = 31610944
881 + 31610063 = 31610944
971 + 31609973 = 31610944
977 + 31609967 = 31610944

Showing the first eight; more decompositions exist.
