Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590094, here are decompositions:

5 + 31590089 = 31590094
23 + 31590071 = 31590094
83 + 31590011 = 31590094
113 + 31589981 = 31590094
227 + 31589867 = 31590094
233 + 31589861 = 31590094
251 + 31589843 = 31590094
317 + 31589777 = 31590094

Showing the first eight; more decompositions exist.
