Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720150, here are decompositions:

13 + 8720137 = 8720150
31 + 8720119 = 8720150
37 + 8720113 = 8720150
79 + 8720071 = 8720150
151 + 8719999 = 8720150
163 + 8719987 = 8720150
199 + 8719951 = 8720150
211 + 8719939 = 8720150

Showing the first eight; more decompositions exist.
