Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594240, here are decompositions:

3 + 31594237 = 31594240
47 + 31594193 = 31594240
89 + 31594151 = 31594240
107 + 31594133 = 31594240
179 + 31594061 = 31594240
191 + 31594049 = 31594240
257 + 31593983 = 31594240
281 + 31593959 = 31594240

Showing the first eight; more decompositions exist.
