Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595404, here are decompositions:

11 + 31595393 = 31595404
17 + 31595387 = 31595404
41 + 31595363 = 31595404
131 + 31595273 = 31595404
167 + 31595237 = 31595404
227 + 31595177 = 31595404
263 + 31595141 = 31595404
383 + 31595021 = 31595404

Showing the first eight; more decompositions exist.
