Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701128, here are decompositions:

5 + 8701123 = 8701128
11 + 8701117 = 8701128
47 + 8701081 = 8701128
61 + 8701067 = 8701128
71 + 8701057 = 8701128
89 + 8701039 = 8701128
101 + 8701027 = 8701128
127 + 8701001 = 8701128

Showing the first eight; more decompositions exist.
