Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590012, here are decompositions:

5 + 31590007 = 31590012
29 + 31589983 = 31590012
31 + 31589981 = 31590012
59 + 31589953 = 31590012
89 + 31589923 = 31590012
151 + 31589861 = 31590012
193 + 31589819 = 31590012
239 + 31589773 = 31590012

Showing the first eight; more decompositions exist.
