Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594192, here are decompositions:

29 + 31594163 = 31594192
41 + 31594151 = 31594192
59 + 31594133 = 31594192
131 + 31594061 = 31594192
233 + 31593959 = 31594192
239 + 31593953 = 31594192
353 + 31593839 = 31594192
359 + 31593833 = 31594192

Showing the first eight; more decompositions exist.
