Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594246, here are decompositions:

53 + 31594193 = 31594246
83 + 31594163 = 31594246
113 + 31594133 = 31594246
149 + 31594097 = 31594246
197 + 31594049 = 31594246
263 + 31593983 = 31594246
293 + 31593953 = 31594246
449 + 31593797 = 31594246

Showing the first eight; more decompositions exist.
