Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720270, here are decompositions:

37 + 8720233 = 8720270
43 + 8720227 = 8720270
79 + 8720191 = 8720270
109 + 8720161 = 8720270
151 + 8720119 = 8720270
157 + 8720113 = 8720270
199 + 8720071 = 8720270
271 + 8719999 = 8720270

Showing the first eight; more decompositions exist.
