Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720234, here are decompositions:

7 + 8720227 = 8720234
43 + 8720191 = 8720234
73 + 8720161 = 8720234
97 + 8720137 = 8720234
163 + 8720071 = 8720234
283 + 8719951 = 8720234
331 + 8719903 = 8720234
421 + 8719813 = 8720234

Showing the first eight; more decompositions exist.
