Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607022, here are decompositions:

43 + 31606979 = 31607022
59 + 31606963 = 31607022
71 + 31606951 = 31607022
79 + 31606943 = 31607022
103 + 31606919 = 31607022
193 + 31606829 = 31607022
211 + 31606811 = 31607022
269 + 31606753 = 31607022

Showing the first eight; more decompositions exist.
