Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608152, here are decompositions:

3 + 31608149 = 31608152
19 + 31608133 = 31608152
61 + 31608091 = 31608152
139 + 31608013 = 31608152
181 + 31607971 = 31608152
283 + 31607869 = 31608152
313 + 31607839 = 31608152
463 + 31607689 = 31608152

Showing the first eight; more decompositions exist.
