Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590294, here are decompositions:

17 + 31590277 = 31590294
31 + 31590263 = 31590294
53 + 31590241 = 31590294
83 + 31590211 = 31590294
107 + 31590187 = 31590294
157 + 31590137 = 31590294
173 + 31590121 = 31590294
223 + 31590071 = 31590294

Showing the first eight; more decompositions exist.
