Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609196, here are decompositions:

7 + 31609189 = 31609196
79 + 31609117 = 31609196
103 + 31609093 = 31609196
109 + 31609087 = 31609196
163 + 31609033 = 31609196
313 + 31608883 = 31609196
373 + 31608823 = 31609196
379 + 31608817 = 31609196

Showing the first eight; more decompositions exist.
