Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712280, here are decompositions:

11 + 8712269 = 8712280
23 + 8712257 = 8712280
47 + 8712233 = 8712280
53 + 8712227 = 8712280
107 + 8712173 = 8712280
113 + 8712167 = 8712280
131 + 8712149 = 8712280
167 + 8712113 = 8712280

Showing the first eight; more decompositions exist.
