Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687832, here are decompositions:

5 + 8687827 = 8687832
61 + 8687771 = 8687832
73 + 8687759 = 8687832
103 + 8687729 = 8687832
163 + 8687669 = 8687832
173 + 8687659 = 8687832
191 + 8687641 = 8687832
229 + 8687603 = 8687832

Showing the first eight; more decompositions exist.
