Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687838, here are decompositions:

11 + 8687827 = 8687838
41 + 8687797 = 8687838
67 + 8687771 = 8687838
79 + 8687759 = 8687838
109 + 8687729 = 8687838
139 + 8687699 = 8687838
151 + 8687687 = 8687838
167 + 8687671 = 8687838

Showing the first eight; more decompositions exist.
