Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594170, here are decompositions:

7 + 31594163 = 31594170
11 + 31594159 = 31594170
19 + 31594151 = 31594170
37 + 31594133 = 31594170
73 + 31594097 = 31594170
89 + 31594081 = 31594170
107 + 31594063 = 31594170
109 + 31594061 = 31594170

Showing the first eight; more decompositions exist.
