Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687530, here are decompositions:

17 + 8687513 = 8687530
53 + 8687477 = 8687530
101 + 8687429 = 8687530
107 + 8687423 = 8687530
149 + 8687381 = 8687530
167 + 8687363 = 8687530
227 + 8687303 = 8687530
239 + 8687291 = 8687530

Showing the first eight; more decompositions exist.
