Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590006, here are decompositions:

23 + 31589983 = 31590006
29 + 31589977 = 31590006
53 + 31589953 = 31590006
83 + 31589923 = 31590006
137 + 31589869 = 31590006
139 + 31589867 = 31590006
163 + 31589843 = 31590006
179 + 31589827 = 31590006

Showing the first eight; more decompositions exist.
