Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589910, here are decompositions:

19 + 31589891 = 31589910
41 + 31589869 = 31589910
43 + 31589867 = 31589910
67 + 31589843 = 31589910
83 + 31589827 = 31589910
137 + 31589773 = 31589910
139 + 31589771 = 31589910
151 + 31589759 = 31589910

Showing the first eight; more decompositions exist.
