Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608124, here are decompositions:

17 + 31608107 = 31608124
83 + 31608041 = 31608124
227 + 31607897 = 31608124
257 + 31607867 = 31608124
293 + 31607831 = 31608124
593 + 31607531 = 31608124
677 + 31607447 = 31608124
701 + 31607423 = 31608124

Showing the first eight; more decompositions exist.
