Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589886, here are decompositions:

17 + 31589869 = 31589886
19 + 31589867 = 31589886
43 + 31589843 = 31589886
59 + 31589827 = 31589886
67 + 31589819 = 31589886
109 + 31589777 = 31589886
113 + 31589773 = 31589886
127 + 31589759 = 31589886

Showing the first eight; more decompositions exist.
