Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594212, here are decompositions:

19 + 31594193 = 31594212
53 + 31594159 = 31594212
61 + 31594151 = 31594212
79 + 31594133 = 31594212
131 + 31594081 = 31594212
149 + 31594063 = 31594212
151 + 31594061 = 31594212
163 + 31594049 = 31594212

Showing the first eight; more decompositions exist.
