Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608150, here are decompositions:

17 + 31608133 = 31608150
19 + 31608131 = 31608150
43 + 31608107 = 31608150
59 + 31608091 = 31608150
83 + 31608067 = 31608150
89 + 31608061 = 31608150
103 + 31608047 = 31608150
109 + 31608041 = 31608150

Showing the first eight; more decompositions exist.
