Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712012, here are decompositions:

41 + 8711971 = 8712012
59 + 8711953 = 8712012
61 + 8711951 = 8712012
79 + 8711933 = 8712012
149 + 8711863 = 8712012
163 + 8711849 = 8712012
191 + 8711821 = 8712012
229 + 8711783 = 8712012

Showing the first eight; more decompositions exist.
