Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711980, here are decompositions:

29 + 8711951 = 8711980
47 + 8711933 = 8711980
59 + 8711921 = 8711980
83 + 8711897 = 8711980
113 + 8711867 = 8711980
131 + 8711849 = 8711980
197 + 8711783 = 8711980
239 + 8711741 = 8711980

Showing the first eight; more decompositions exist.
