Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608032, here are decompositions:

3 + 31608029 = 31608032
19 + 31608013 = 31608032
61 + 31607971 = 31608032
163 + 31607869 = 31608032
193 + 31607839 = 31608032
241 + 31607791 = 31608032
349 + 31607683 = 31608032
433 + 31607599 = 31608032

Showing the first eight; more decompositions exist.
