Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645398, here are decompositions:

17 + 8645381 = 8645398
71 + 8645327 = 8645398
131 + 8645267 = 8645398
137 + 8645261 = 8645398
257 + 8645141 = 8645398
317 + 8645081 = 8645398
389 + 8645009 = 8645398
449 + 8644949 = 8645398

Showing the first eight; more decompositions exist.
