Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590054, here are decompositions:

17 + 31590037 = 31590054
43 + 31590011 = 31590054
47 + 31590007 = 31590054
71 + 31589983 = 31590054
73 + 31589981 = 31590054
101 + 31589953 = 31590054
131 + 31589923 = 31590054
163 + 31589891 = 31590054

Showing the first eight; more decompositions exist.
