Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608070, here are decompositions:

3 + 31608067 = 31608070
23 + 31608047 = 31608070
29 + 31608041 = 31608070
41 + 31608029 = 31608070
101 + 31607969 = 31608070
149 + 31607921 = 31608070
167 + 31607903 = 31608070
173 + 31607897 = 31608070

Showing the first eight; more decompositions exist.
