Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609608, here are decompositions:

31 + 31609577 = 31609608
47 + 31609561 = 31609608
59 + 31609549 = 31609608
61 + 31609547 = 31609608
67 + 31609541 = 31609608
89 + 31609519 = 31609608
109 + 31609499 = 31609608
127 + 31609481 = 31609608

Showing the first eight; more decompositions exist.
