Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594120, here are decompositions:

23 + 31594097 = 31594120
59 + 31594061 = 31594120
71 + 31594049 = 31594120
137 + 31593983 = 31594120
167 + 31593953 = 31594120
251 + 31593869 = 31594120
281 + 31593839 = 31594120
353 + 31593767 = 31594120

Showing the first eight; more decompositions exist.
