Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681106, here are decompositions:

17 + 8681089 = 8681106
29 + 8681077 = 8681106
47 + 8681059 = 8681106
59 + 8681047 = 8681106
97 + 8681009 = 8681106
103 + 8681003 = 8681106
113 + 8680993 = 8681106
167 + 8680939 = 8681106

Showing the first eight; more decompositions exist.
