Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609710, here are decompositions:

7 + 31609703 = 31609710
17 + 31609693 = 31609710
19 + 31609691 = 31609710
31 + 31609679 = 31609710
79 + 31609631 = 31609710
101 + 31609609 = 31609710
127 + 31609583 = 31609710
149 + 31609561 = 31609710

Showing the first eight; more decompositions exist.
