Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595400, here are decompositions:

7 + 31595393 = 31595400
13 + 31595387 = 31595400
17 + 31595383 = 31595400
29 + 31595371 = 31595400
37 + 31595363 = 31595400
127 + 31595273 = 31595400
149 + 31595251 = 31595400
157 + 31595243 = 31595400

Showing the first eight; more decompositions exist.
