Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687488, here are decompositions:

11 + 8687477 = 8687488
59 + 8687429 = 8687488
101 + 8687387 = 8687488
107 + 8687381 = 8687488
167 + 8687321 = 8687488
179 + 8687309 = 8687488
197 + 8687291 = 8687488
239 + 8687249 = 8687488

Showing the first eight; more decompositions exist.
