Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704388, here are decompositions:

19 + 8704369 = 8704388
37 + 8704351 = 8704388
79 + 8704309 = 8704388
109 + 8704279 = 8704388
229 + 8704159 = 8704388
271 + 8704117 = 8704388
499 + 8703889 = 8704388
547 + 8703841 = 8704388

Showing the first eight; more decompositions exist.
