Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704128, here are decompositions:

5 + 8704123 = 8704128
7 + 8704121 = 8704128
11 + 8704117 = 8704128
61 + 8704067 = 8704128
79 + 8704049 = 8704128
101 + 8704027 = 8704128
157 + 8703971 = 8704128
229 + 8703899 = 8704128

Showing the first eight; more decompositions exist.
