Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736872, here are decompositions:

19 + 8736853 = 8736872
73 + 8736799 = 8736872
241 + 8736631 = 8736872
409 + 8736463 = 8736872
439 + 8736433 = 8736872
673 + 8736199 = 8736872
733 + 8736139 = 8736872
811 + 8736061 = 8736872

Showing the first eight; more decompositions exist.
