Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594188, here are decompositions:

29 + 31594159 = 31594188
37 + 31594151 = 31594188
107 + 31594081 = 31594188
127 + 31594061 = 31594188
139 + 31594049 = 31594188
149 + 31594039 = 31594188
229 + 31593959 = 31594188
251 + 31593937 = 31594188

Showing the first eight; more decompositions exist.
