Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597440, here are decompositions:

23 + 8597417 = 8597440
101 + 8597339 = 8597440
227 + 8597213 = 8597440
281 + 8597159 = 8597440
317 + 8597123 = 8597440
347 + 8597093 = 8597440
359 + 8597081 = 8597440
389 + 8597051 = 8597440

Showing the first eight; more decompositions exist.
