Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608062, here are decompositions:

193 + 31607869 = 31608062
223 + 31607839 = 31608062
271 + 31607791 = 31608062
373 + 31607689 = 31608062
379 + 31607683 = 31608062
433 + 31607629 = 31608062
463 + 31607599 = 31608062
601 + 31607461 = 31608062

Showing the first eight; more decompositions exist.
