Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654778, here are decompositions:

5 + 8654773 = 8654778
7 + 8654771 = 8654778
17 + 8654761 = 8654778
19 + 8654759 = 8654778
29 + 8654749 = 8654778
89 + 8654689 = 8654778
137 + 8654641 = 8654778
157 + 8654621 = 8654778

Showing the first eight; more decompositions exist.
