Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590024, here are decompositions:

13 + 31590011 = 31590024
17 + 31590007 = 31590024
41 + 31589983 = 31590024
43 + 31589981 = 31590024
47 + 31589977 = 31590024
71 + 31589953 = 31590024
101 + 31589923 = 31590024
157 + 31589867 = 31590024

Showing the first eight; more decompositions exist.
