Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687244, here are decompositions:

11 + 8687233 = 8687244
17 + 8687227 = 8687244
31 + 8687213 = 8687244
37 + 8687207 = 8687244
47 + 8687197 = 8687244
61 + 8687183 = 8687244
73 + 8687171 = 8687244
103 + 8687141 = 8687244

Showing the first eight; more decompositions exist.
