Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597220, here are decompositions:

7 + 8597213 = 8597220
17 + 8597203 = 8597220
41 + 8597179 = 8597220
61 + 8597159 = 8597220
97 + 8597123 = 8597220
103 + 8597117 = 8597220
109 + 8597111 = 8597220
127 + 8597093 = 8597220

Showing the first eight; more decompositions exist.
