Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594360, here are decompositions:

29 + 31594331 = 31594360
89 + 31594271 = 31594360
113 + 31594247 = 31594360
167 + 31594193 = 31594360
197 + 31594163 = 31594360
227 + 31594133 = 31594360
263 + 31594097 = 31594360
311 + 31594049 = 31594360

Showing the first eight; more decompositions exist.
