Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607822, here are decompositions:

31 + 31607791 = 31607822
139 + 31607683 = 31607822
151 + 31607671 = 31607822
193 + 31607629 = 31607822
223 + 31607599 = 31607822
241 + 31607581 = 31607822
271 + 31607551 = 31607822
349 + 31607473 = 31607822

Showing the first eight; more decompositions exist.
