Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594260, here are decompositions:

13 + 31594247 = 31594260
23 + 31594237 = 31594260
67 + 31594193 = 31594260
97 + 31594163 = 31594260
101 + 31594159 = 31594260
109 + 31594151 = 31594260
127 + 31594133 = 31594260
163 + 31594097 = 31594260

Showing the first eight; more decompositions exist.
