Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699220, here are decompositions:

41 + 8699179 = 8699220
53 + 8699167 = 8699220
59 + 8699161 = 8699220
107 + 8699113 = 8699220
151 + 8699069 = 8699220
157 + 8699063 = 8699220
181 + 8699039 = 8699220
223 + 8698997 = 8699220

Showing the first eight; more decompositions exist.
