Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609036, here are decompositions:

3 + 31609033 = 31609036
5 + 31609031 = 31609036
83 + 31608953 = 31609036
149 + 31608887 = 31609036
257 + 31608779 = 31609036
449 + 31608587 = 31609036
509 + 31608527 = 31609036
587 + 31608449 = 31609036

Showing the first eight; more decompositions exist.
