Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687322, here are decompositions:

5 + 8687317 = 8687322
13 + 8687309 = 8687322
19 + 8687303 = 8687322
23 + 8687299 = 8687322
31 + 8687291 = 8687322
73 + 8687249 = 8687322
89 + 8687233 = 8687322
109 + 8687213 = 8687322

Showing the first eight; more decompositions exist.
