Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712064, here are decompositions:

5 + 8712059 = 8712064
47 + 8712017 = 8712064
113 + 8711951 = 8712064
131 + 8711933 = 8712064
167 + 8711897 = 8712064
197 + 8711867 = 8712064
281 + 8711783 = 8712064
443 + 8711621 = 8712064

Showing the first eight; more decompositions exist.
