Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594290, here are decompositions:

17 + 31594273 = 31594290
19 + 31594271 = 31594290
43 + 31594247 = 31594290
53 + 31594237 = 31594290
97 + 31594193 = 31594290
127 + 31594163 = 31594290
131 + 31594159 = 31594290
139 + 31594151 = 31594290

Showing the first eight; more decompositions exist.
