Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687538, here are decompositions:

17 + 8687521 = 8687538
59 + 8687479 = 8687538
61 + 8687477 = 8687538
71 + 8687467 = 8687538
109 + 8687429 = 8687538
137 + 8687401 = 8687538
151 + 8687387 = 8687538
157 + 8687381 = 8687538

Showing the first eight; more decompositions exist.
