Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39898, here are decompositions:

11 + 39887 = 39898
29 + 39869 = 39898
41 + 39857 = 39898
59 + 39839 = 39898
71 + 39827 = 39898
107 + 39791 = 39898
137 + 39761 = 39898
149 + 39749 = 39898

Showing the first eight; more decompositions exist.
