Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597218, here are decompositions:

5 + 8597213 = 8597218
59 + 8597159 = 8597218
101 + 8597117 = 8597218
107 + 8597111 = 8597218
137 + 8597081 = 8597218
167 + 8597051 = 8597218
191 + 8597027 = 8597218
239 + 8596979 = 8597218

Showing the first eight; more decompositions exist.
