Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609532, here are decompositions:

13 + 31609519 = 31609532
79 + 31609453 = 31609532
139 + 31609393 = 31609532
151 + 31609381 = 31609532
193 + 31609339 = 31609532
421 + 31609111 = 31609532
439 + 31609093 = 31609532
499 + 31609033 = 31609532

Showing the first eight; more decompositions exist.
