Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590088, here are decompositions:

17 + 31590071 = 31590088
107 + 31589981 = 31590088
197 + 31589891 = 31590088
227 + 31589861 = 31590088
269 + 31589819 = 31590088
311 + 31589777 = 31590088
317 + 31589771 = 31590088
521 + 31589567 = 31590088

Showing the first eight; more decompositions exist.
