Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594206, here are decompositions:

13 + 31594193 = 31594206
43 + 31594163 = 31594206
47 + 31594159 = 31594206
73 + 31594133 = 31594206
109 + 31594097 = 31594206
157 + 31594049 = 31594206
167 + 31594039 = 31594206
223 + 31593983 = 31594206

Showing the first eight; more decompositions exist.
