Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609934, here are decompositions:

3 + 31609931 = 31609934
73 + 31609861 = 31609934
157 + 31609777 = 31609934
193 + 31609741 = 31609934
211 + 31609723 = 31609934
241 + 31609693 = 31609934
373 + 31609561 = 31609934
541 + 31609393 = 31609934

Showing the first eight; more decompositions exist.
