Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711986, here are decompositions:

53 + 8711933 = 8711986
89 + 8711897 = 8711986
137 + 8711849 = 8711986
317 + 8711669 = 8711986
359 + 8711627 = 8711986
383 + 8711603 = 8711986
443 + 8711543 = 8711986
587 + 8711399 = 8711986

Showing the first eight; more decompositions exist.
