Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712018, here are decompositions:

31 + 8711987 = 8712018
47 + 8711971 = 8712018
67 + 8711951 = 8712018
97 + 8711921 = 8712018
131 + 8711887 = 8712018
149 + 8711869 = 8712018
151 + 8711867 = 8712018
167 + 8711851 = 8712018

Showing the first eight; more decompositions exist.
