Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590010, here are decompositions:

3 + 31590007 = 31590010
29 + 31589981 = 31590010
149 + 31589861 = 31590010
167 + 31589843 = 31590010
191 + 31589819 = 31590010
233 + 31589777 = 31590010
239 + 31589771 = 31590010
251 + 31589759 = 31590010

Showing the first eight; more decompositions exist.
