Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712864, here are decompositions:

5 + 8712859 = 8712864
37 + 8712827 = 8712864
71 + 8712793 = 8712864
103 + 8712761 = 8712864
107 + 8712757 = 8712864
113 + 8712751 = 8712864
137 + 8712727 = 8712864
151 + 8712713 = 8712864

Showing the first eight; more decompositions exist.
