Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609112, here are decompositions:

19 + 31609093 = 31609112
79 + 31609033 = 31609112
229 + 31608883 = 31609112
523 + 31608589 = 31609112
631 + 31608481 = 31609112
811 + 31608301 = 31609112
1021 + 31608091 = 31609112
1051 + 31608061 = 31609112

Showing the first eight; more decompositions exist.
