Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609976, here are decompositions:

3 + 31609973 = 31609976
19 + 31609957 = 31609976
43 + 31609933 = 31609976
127 + 31609849 = 31609976
157 + 31609819 = 31609976
163 + 31609813 = 31609976
199 + 31609777 = 31609976
283 + 31609693 = 31609976

Showing the first eight; more decompositions exist.
