Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711998, here are decompositions:

11 + 8711987 = 8711998
47 + 8711951 = 8711998
101 + 8711897 = 8711998
131 + 8711867 = 8711998
149 + 8711849 = 8711998
257 + 8711741 = 8711998
509 + 8711489 = 8711998
599 + 8711399 = 8711998

Showing the first eight; more decompositions exist.
