Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728926, here are decompositions:

5 + 8728921 = 8728926
23 + 8728903 = 8728926
29 + 8728897 = 8728926
43 + 8728883 = 8728926
103 + 8728823 = 8728926
139 + 8728787 = 8728926
263 + 8728663 = 8728926
277 + 8728649 = 8728926

Showing the first eight; more decompositions exist.
