Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736740, here are decompositions:

13 + 8736727 = 8736740
37 + 8736703 = 8736740
73 + 8736667 = 8736740
109 + 8736631 = 8736740
157 + 8736583 = 8736740
193 + 8736547 = 8736740
211 + 8736529 = 8736740
277 + 8736463 = 8736740

Showing the first eight; more decompositions exist.
