Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704728, here are decompositions:

5 + 8704723 = 8704728
7 + 8704721 = 8704728
17 + 8704711 = 8704728
29 + 8704699 = 8704728
37 + 8704691 = 8704728
41 + 8704687 = 8704728
107 + 8704621 = 8704728
127 + 8704601 = 8704728

Showing the first eight; more decompositions exist.
