Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736648, here are decompositions:

17 + 8736631 = 8736648
31 + 8736617 = 8736648
101 + 8736547 = 8736648
139 + 8736509 = 8736648
199 + 8736449 = 8736648
281 + 8736367 = 8736648
307 + 8736341 = 8736648
439 + 8736209 = 8736648

Showing the first eight; more decompositions exist.
