Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645248, here are decompositions:

5 + 8645243 = 8645248
11 + 8645237 = 8645248
107 + 8645141 = 8645248
167 + 8645081 = 8645248
239 + 8645009 = 8645248
257 + 8644991 = 8645248
449 + 8644799 = 8645248
467 + 8644781 = 8645248

Showing the first eight; more decompositions exist.
