Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594254, here are decompositions:

7 + 31594247 = 31594254
17 + 31594237 = 31594254
61 + 31594193 = 31594254
103 + 31594151 = 31594254
157 + 31594097 = 31594254
173 + 31594081 = 31594254
191 + 31594063 = 31594254
193 + 31594061 = 31594254

Showing the first eight; more decompositions exist.
