Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745816, here are decompositions:

17 + 8745799 = 8745816
67 + 8745749 = 8745816
73 + 8745743 = 8745816
113 + 8745703 = 8745816
137 + 8745679 = 8745816
139 + 8745677 = 8745816
179 + 8745637 = 8745816
263 + 8745553 = 8745816

Showing the first eight; more decompositions exist.
