Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687278, here are decompositions:

29 + 8687249 = 8687278
71 + 8687207 = 8687278
107 + 8687171 = 8687278
137 + 8687141 = 8687278
191 + 8687087 = 8687278
251 + 8687027 = 8687278
317 + 8686961 = 8687278
389 + 8686889 = 8687278

Showing the first eight; more decompositions exist.
