Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609588, here are decompositions:

5 + 31609583 = 31609588
11 + 31609577 = 31609588
41 + 31609547 = 31609588
47 + 31609541 = 31609588
89 + 31609499 = 31609588
107 + 31609481 = 31609588
137 + 31609451 = 31609588
359 + 31609229 = 31609588

Showing the first eight; more decompositions exist.
