Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608006, here are decompositions:

37 + 31607969 = 31608006
97 + 31607909 = 31608006
103 + 31607903 = 31608006
109 + 31607897 = 31608006
137 + 31607869 = 31608006
139 + 31607867 = 31608006
149 + 31607857 = 31608006
167 + 31607839 = 31608006

Showing the first eight; more decompositions exist.
