Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687390, here are decompositions:

3 + 8687387 = 8687390
7 + 8687383 = 8687390
31 + 8687359 = 8687390
73 + 8687317 = 8687390
157 + 8687233 = 8687390
163 + 8687227 = 8687390
181 + 8687209 = 8687390
193 + 8687197 = 8687390

Showing the first eight; more decompositions exist.
