Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736800, here are decompositions:

13 + 8736787 = 8736800
19 + 8736781 = 8736800
73 + 8736727 = 8736800
97 + 8736703 = 8736800
271 + 8736529 = 8736800
337 + 8736463 = 8736800
367 + 8736433 = 8736800
433 + 8736367 = 8736800

Showing the first eight; more decompositions exist.
