Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609304, here are decompositions:

37 + 31609267 = 31609304
73 + 31609231 = 31609304
193 + 31609111 = 31609304
211 + 31609093 = 31609304
271 + 31609033 = 31609304
367 + 31608937 = 31609304
421 + 31608883 = 31609304
487 + 31608817 = 31609304

Showing the first eight; more decompositions exist.
