Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607610, here are decompositions:

11 + 31607599 = 31607610
29 + 31607581 = 31607610
31 + 31607579 = 31607610
59 + 31607551 = 31607610
79 + 31607531 = 31607610
107 + 31607503 = 31607610
137 + 31607473 = 31607610
149 + 31607461 = 31607610

Showing the first eight; more decompositions exist.
