Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736680, here are decompositions:

13 + 8736667 = 8736680
97 + 8736583 = 8736680
151 + 8736529 = 8736680
313 + 8736367 = 8736680
457 + 8736223 = 8736680
541 + 8736139 = 8736680
571 + 8736109 = 8736680
607 + 8736073 = 8736680

Showing the first eight; more decompositions exist.
