Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728916, here are decompositions:

13 + 8728903 = 8728916
19 + 8728897 = 8728916
67 + 8728849 = 8728916
109 + 8728807 = 8728916
199 + 8728717 = 8728916
307 + 8728609 = 8728916
337 + 8728579 = 8728916
367 + 8728549 = 8728916

Showing the first eight; more decompositions exist.
