Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590066, here are decompositions:

5 + 31590061 = 31590066
29 + 31590037 = 31590066
59 + 31590007 = 31590066
83 + 31589983 = 31590066
89 + 31589977 = 31590066
113 + 31589953 = 31590066
197 + 31589869 = 31590066
199 + 31589867 = 31590066

Showing the first eight; more decompositions exist.
