Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590022, here are decompositions:

11 + 31590011 = 31590022
41 + 31589981 = 31590022
131 + 31589891 = 31590022
179 + 31589843 = 31590022
251 + 31589771 = 31590022
263 + 31589759 = 31590022
311 + 31589711 = 31590022
389 + 31589633 = 31590022

Showing the first eight; more decompositions exist.
