Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703688, here are decompositions:

29 + 8703659 = 8703688
47 + 8703641 = 8703688
107 + 8703581 = 8703688
137 + 8703551 = 8703688
197 + 8703491 = 8703688
311 + 8703377 = 8703688
401 + 8703287 = 8703688
431 + 8703257 = 8703688

Showing the first eight; more decompositions exist.
