Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720288, here are decompositions:

7 + 8720281 = 8720288
61 + 8720227 = 8720288
97 + 8720191 = 8720288
127 + 8720161 = 8720288
151 + 8720137 = 8720288
337 + 8719951 = 8720288
349 + 8719939 = 8720288
457 + 8719831 = 8720288

Showing the first eight; more decompositions exist.
