Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687458, here are decompositions:

5 + 8687453 = 8687458
29 + 8687429 = 8687458
71 + 8687387 = 8687458
89 + 8687369 = 8687458
137 + 8687321 = 8687458
149 + 8687309 = 8687458
167 + 8687291 = 8687458
251 + 8687207 = 8687458

Showing the first eight; more decompositions exist.
