Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728692, here are decompositions:

13 + 8728679 = 8728692
29 + 8728663 = 8728692
43 + 8728649 = 8728692
83 + 8728609 = 8728692
101 + 8728591 = 8728692
113 + 8728579 = 8728692
179 + 8728513 = 8728692
211 + 8728481 = 8728692

Showing the first eight; more decompositions exist.
