Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594230, here are decompositions:

37 + 31594193 = 31594230
67 + 31594163 = 31594230
71 + 31594159 = 31594230
79 + 31594151 = 31594230
97 + 31594133 = 31594230
149 + 31594081 = 31594230
167 + 31594063 = 31594230
181 + 31594049 = 31594230

Showing the first eight; more decompositions exist.
