Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589898, here are decompositions:

7 + 31589891 = 31589898
29 + 31589869 = 31589898
31 + 31589867 = 31589898
37 + 31589861 = 31589898
71 + 31589827 = 31589898
79 + 31589819 = 31589898
127 + 31589771 = 31589898
139 + 31589759 = 31589898

Showing the first eight; more decompositions exist.
