Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608050, here are decompositions:

3 + 31608047 = 31608050
13 + 31608037 = 31608050
37 + 31608013 = 31608050
79 + 31607971 = 31608050
181 + 31607869 = 31608050
193 + 31607857 = 31608050
211 + 31607839 = 31608050
367 + 31607683 = 31608050

Showing the first eight; more decompositions exist.
