Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687844, here are decompositions:

17 + 8687827 = 8687844
47 + 8687797 = 8687844
73 + 8687771 = 8687844
131 + 8687713 = 8687844
157 + 8687687 = 8687844
173 + 8687671 = 8687844
241 + 8687603 = 8687844
257 + 8687587 = 8687844

Showing the first eight; more decompositions exist.
