Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595200, here are decompositions:

11 + 31595189 = 31595200
23 + 31595177 = 31595200
59 + 31595141 = 31595200
137 + 31595063 = 31595200
179 + 31595021 = 31595200
191 + 31595009 = 31595200
239 + 31594961 = 31595200
269 + 31594931 = 31595200

Showing the first eight; more decompositions exist.
