Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684228, here are decompositions:

97 + 8684131 = 8684228
139 + 8684089 = 8684228
151 + 8684077 = 8684228
181 + 8684047 = 8684228
199 + 8684029 = 8684228
331 + 8683897 = 8684228
499 + 8683729 = 8684228
541 + 8683687 = 8684228

Showing the first eight; more decompositions exist.
