Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597420, here are decompositions:

3 + 8597417 = 8597420
67 + 8597353 = 8597420
79 + 8597341 = 8597420
103 + 8597317 = 8597420
127 + 8597293 = 8597420
157 + 8597263 = 8597420
193 + 8597227 = 8597420
241 + 8597179 = 8597420

Showing the first eight; more decompositions exist.
