Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687524, here are decompositions:

3 + 8687521 = 8687524
11 + 8687513 = 8687524
47 + 8687477 = 8687524
71 + 8687453 = 8687524
101 + 8687423 = 8687524
137 + 8687387 = 8687524
233 + 8687291 = 8687524
311 + 8687213 = 8687524

Showing the first eight; more decompositions exist.
