Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590016, here are decompositions:

5 + 31590011 = 31590016
149 + 31589867 = 31590016
173 + 31589843 = 31590016
197 + 31589819 = 31590016
239 + 31589777 = 31590016
257 + 31589759 = 31590016
383 + 31589633 = 31590016
449 + 31589567 = 31590016

Showing the first eight; more decompositions exist.
