Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681088, here are decompositions:

11 + 8681077 = 8681088
29 + 8681059 = 8681088
41 + 8681047 = 8681088
67 + 8681021 = 8681088
79 + 8681009 = 8681088
137 + 8680951 = 8681088
149 + 8680939 = 8681088
167 + 8680921 = 8681088

Showing the first eight; more decompositions exist.
