Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720352, here are decompositions:

5 + 8720347 = 8720352
13 + 8720339 = 8720352
31 + 8720321 = 8720352
41 + 8720311 = 8720352
71 + 8720281 = 8720352
163 + 8720189 = 8720352
181 + 8720171 = 8720352
191 + 8720161 = 8720352

Showing the first eight; more decompositions exist.
