Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728084, here are decompositions:

5 + 8728079 = 8728084
11 + 8728073 = 8728084
47 + 8728037 = 8728084
227 + 8727857 = 8728084
293 + 8727791 = 8728084
311 + 8727773 = 8728084
317 + 8727767 = 8728084
353 + 8727731 = 8728084

Showing the first eight; more decompositions exist.
