Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595622, here are decompositions:

11 + 31595611 = 31595622
29 + 31595593 = 31595622
41 + 31595581 = 31595622
53 + 31595569 = 31595622
139 + 31595483 = 31595622
229 + 31595393 = 31595622
239 + 31595383 = 31595622
251 + 31595371 = 31595622

Showing the first eight; more decompositions exist.
