Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736320, here are decompositions:

97 + 8736223 = 8736320
181 + 8736139 = 8736320
193 + 8736127 = 8736320
211 + 8736109 = 8736320
223 + 8736097 = 8736320
283 + 8736037 = 8736320
349 + 8735971 = 8736320
379 + 8735941 = 8736320

Showing the first eight; more decompositions exist.
