Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609602, here are decompositions:

19 + 31609583 = 31609602
41 + 31609561 = 31609602
53 + 31609549 = 31609602
61 + 31609541 = 31609602
71 + 31609531 = 31609602
83 + 31609519 = 31609602
103 + 31609499 = 31609602
109 + 31609493 = 31609602

Showing the first eight; more decompositions exist.
