Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687588, here are decompositions:

67 + 8687521 = 8687588
109 + 8687479 = 8687588
127 + 8687461 = 8687588
229 + 8687359 = 8687588
271 + 8687317 = 8687588
379 + 8687209 = 8687588
439 + 8687149 = 8687588
457 + 8687131 = 8687588

Showing the first eight; more decompositions exist.
