Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687286, here are decompositions:

37 + 8687249 = 8687286
53 + 8687233 = 8687286
59 + 8687227 = 8687286
73 + 8687213 = 8687286
79 + 8687207 = 8687286
89 + 8687197 = 8687286
103 + 8687183 = 8687286
137 + 8687149 = 8687286

Showing the first eight; more decompositions exist.
