Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711928, here are decompositions:

7 + 8711921 = 8711928
31 + 8711897 = 8711928
41 + 8711887 = 8711928
59 + 8711869 = 8711928
61 + 8711867 = 8711928
79 + 8711849 = 8711928
107 + 8711821 = 8711928
131 + 8711797 = 8711928

Showing the first eight; more decompositions exist.
