Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687586, here are decompositions:

73 + 8687513 = 8687586
107 + 8687479 = 8687586
109 + 8687477 = 8687586
157 + 8687429 = 8687586
163 + 8687423 = 8687586
199 + 8687387 = 8687586
223 + 8687363 = 8687586
227 + 8687359 = 8687586

Showing the first eight; more decompositions exist.
