Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618448, here are decompositions:

5 + 8618443 = 8618448
19 + 8618429 = 8618448
61 + 8618387 = 8618448
71 + 8618377 = 8618448
109 + 8618339 = 8618448
131 + 8618317 = 8618448
151 + 8618297 = 8618448
191 + 8618257 = 8618448

Showing the first eight; more decompositions exist.
