Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608054, here are decompositions:

7 + 31608047 = 31608054
13 + 31608041 = 31608054
17 + 31608037 = 31608054
41 + 31608013 = 31608054
83 + 31607971 = 31608054
151 + 31607903 = 31608054
157 + 31607897 = 31608054
197 + 31607857 = 31608054

Showing the first eight; more decompositions exist.
