Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698728, here are decompositions:

29 + 8698699 = 8698728
47 + 8698681 = 8698728
89 + 8698639 = 8698728
107 + 8698621 = 8698728
131 + 8698597 = 8698728
179 + 8698549 = 8698728
211 + 8698517 = 8698728
229 + 8698499 = 8698728

Showing the first eight; more decompositions exist.
