Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720330, here are decompositions:

13 + 8720317 = 8720330
19 + 8720311 = 8720330
97 + 8720233 = 8720330
103 + 8720227 = 8720330
139 + 8720191 = 8720330
193 + 8720137 = 8720330
211 + 8720119 = 8720330
331 + 8719999 = 8720330

Showing the first eight; more decompositions exist.
