Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609822, here are decompositions:

3 + 31609819 = 31609822
29 + 31609793 = 31609822
53 + 31609769 = 31609822
131 + 31609691 = 31609822
191 + 31609631 = 31609822
239 + 31609583 = 31609822
281 + 31609541 = 31609822
353 + 31609469 = 31609822

Showing the first eight; more decompositions exist.
