Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712028, here are decompositions:

11 + 8712017 = 8712028
41 + 8711987 = 8712028
107 + 8711921 = 8712028
131 + 8711897 = 8712028
179 + 8711849 = 8712028
251 + 8711777 = 8712028
359 + 8711669 = 8712028
401 + 8711627 = 8712028

Showing the first eight; more decompositions exist.
