Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590082, here are decompositions:

11 + 31590071 = 31590082
71 + 31590011 = 31590082
101 + 31589981 = 31590082
191 + 31589891 = 31590082
239 + 31589843 = 31590082
263 + 31589819 = 31590082
311 + 31589771 = 31590082
389 + 31589693 = 31590082

Showing the first eight; more decompositions exist.
