Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681118, here are decompositions:

7 + 8681111 = 8681118
29 + 8681089 = 8681118
41 + 8681077 = 8681118
59 + 8681059 = 8681118
71 + 8681047 = 8681118
97 + 8681021 = 8681118
109 + 8681009 = 8681118
167 + 8680951 = 8681118

Showing the first eight; more decompositions exist.
