Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695728, here are decompositions:

5 + 8695723 = 8695728
47 + 8695681 = 8695728
61 + 8695667 = 8695728
89 + 8695639 = 8695728
127 + 8695601 = 8695728
137 + 8695591 = 8695728
157 + 8695571 = 8695728
179 + 8695549 = 8695728

Showing the first eight; more decompositions exist.
