Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695220, here are decompositions:

7 + 8695213 = 8695220
13 + 8695207 = 8695220
19 + 8695201 = 8695220
73 + 8695147 = 8695220
103 + 8695117 = 8695220
151 + 8695069 = 8695220
211 + 8695009 = 8695220
229 + 8694991 = 8695220

Showing the first eight; more decompositions exist.
