Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736578, here are decompositions:

31 + 8736547 = 8736578
211 + 8736367 = 8736578
379 + 8736199 = 8736578
439 + 8736139 = 8736578
541 + 8736037 = 8736578
577 + 8736001 = 8736578
607 + 8735971 = 8736578
727 + 8735851 = 8736578

Showing the first eight; more decompositions exist.
