Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597428, here are decompositions:

11 + 8597417 = 8597428
89 + 8597339 = 8597428
107 + 8597321 = 8597428
131 + 8597297 = 8597428
269 + 8597159 = 8597428
311 + 8597117 = 8597428
317 + 8597111 = 8597428
347 + 8597081 = 8597428

Showing the first eight; more decompositions exist.
