Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609952, here are decompositions:

19 + 31609933 = 31609952
103 + 31609849 = 31609952
139 + 31609813 = 31609952
193 + 31609759 = 31609952
211 + 31609741 = 31609952
229 + 31609723 = 31609952
421 + 31609531 = 31609952
433 + 31609519 = 31609952

Showing the first eight; more decompositions exist.
