Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609684, here are decompositions:

5 + 31609679 = 31609684
23 + 31609661 = 31609684
53 + 31609631 = 31609684
101 + 31609583 = 31609684
107 + 31609577 = 31609684
137 + 31609547 = 31609684
191 + 31609493 = 31609684
233 + 31609451 = 31609684

Showing the first eight; more decompositions exist.
