Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608046, here are decompositions:

5 + 31608041 = 31608046
17 + 31608029 = 31608046
137 + 31607909 = 31608046
149 + 31607897 = 31608046
179 + 31607867 = 31608046
257 + 31607789 = 31608046
263 + 31607783 = 31608046
359 + 31607687 = 31608046

Showing the first eight; more decompositions exist.
