Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594038, here are decompositions:

79 + 31593959 = 31594038
101 + 31593937 = 31594038
107 + 31593931 = 31594038
137 + 31593901 = 31594038
199 + 31593839 = 31594038
241 + 31593797 = 31594038
251 + 31593787 = 31594038
271 + 31593767 = 31594038

Showing the first eight; more decompositions exist.
