Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736128, here are decompositions:

19 + 8736109 = 8736128
31 + 8736097 = 8736128
67 + 8736061 = 8736128
127 + 8736001 = 8736128
157 + 8735971 = 8736128
277 + 8735851 = 8736128
307 + 8735821 = 8736128
367 + 8735761 = 8736128

Showing the first eight; more decompositions exist.
