Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711878, here are decompositions:

11 + 8711867 = 8711878
29 + 8711849 = 8711878
101 + 8711777 = 8711878
137 + 8711741 = 8711878
251 + 8711627 = 8711878
257 + 8711621 = 8711878
317 + 8711561 = 8711878
389 + 8711489 = 8711878

Showing the first eight; more decompositions exist.
