Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704238, here are decompositions:

19 + 8704219 = 8704238
79 + 8704159 = 8704238
211 + 8704027 = 8704238
349 + 8703889 = 8704238
379 + 8703859 = 8704238
397 + 8703841 = 8704238
409 + 8703829 = 8704238
421 + 8703817 = 8704238

Showing the first eight; more decompositions exist.
