Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728816, here are decompositions:

29 + 8728787 = 8728816
59 + 8728757 = 8728816
137 + 8728679 = 8728816
167 + 8728649 = 8728816
359 + 8728457 = 8728816
389 + 8728427 = 8728816
419 + 8728397 = 8728816
443 + 8728373 = 8728816

Showing the first eight; more decompositions exist.
