Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618788, here are decompositions:

5 + 8618783 = 8618788
29 + 8618759 = 8618788
41 + 8618747 = 8618788
89 + 8618699 = 8618788
107 + 8618681 = 8618788
149 + 8618639 = 8618788
197 + 8618591 = 8618788
359 + 8618429 = 8618788

Showing the first eight; more decompositions exist.
