Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595422, here are decompositions:

29 + 31595393 = 31595422
59 + 31595363 = 31595422
149 + 31595273 = 31595422
179 + 31595243 = 31595422
233 + 31595189 = 31595422
281 + 31595141 = 31595422
359 + 31595063 = 31595422
401 + 31595021 = 31595422

Showing the first eight; more decompositions exist.
