Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609636, here are decompositions:

5 + 31609631 = 31609636
53 + 31609583 = 31609636
59 + 31609577 = 31609636
89 + 31609547 = 31609636
137 + 31609499 = 31609636
167 + 31609469 = 31609636
173 + 31609463 = 31609636
347 + 31609289 = 31609636

Showing the first eight; more decompositions exist.
