Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594140, here are decompositions:

7 + 31594133 = 31594140
43 + 31594097 = 31594140
59 + 31594081 = 31594140
79 + 31594061 = 31594140
101 + 31594039 = 31594140
157 + 31593983 = 31594140
181 + 31593959 = 31594140
197 + 31593943 = 31594140

Showing the first eight; more decompositions exist.
