Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594282, here are decompositions:

11 + 31594271 = 31594282
89 + 31594193 = 31594282
131 + 31594151 = 31594282
149 + 31594133 = 31594282
233 + 31594049 = 31594282
443 + 31593839 = 31594282
449 + 31593833 = 31594282
563 + 31593719 = 31594282

Showing the first eight; more decompositions exist.
