Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687542, here are decompositions:

29 + 8687513 = 8687542
89 + 8687453 = 8687542
113 + 8687429 = 8687542
173 + 8687369 = 8687542
179 + 8687363 = 8687542
233 + 8687309 = 8687542
239 + 8687303 = 8687542
251 + 8687291 = 8687542

Showing the first eight; more decompositions exist.
