Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609682, here are decompositions:

3 + 31609679 = 31609682
73 + 31609609 = 31609682
151 + 31609531 = 31609682
163 + 31609519 = 31609682
229 + 31609453 = 31609682
571 + 31609111 = 31609682
829 + 31608853 = 31609682
859 + 31608823 = 31609682

Showing the first eight; more decompositions exist.
