Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681066, here are decompositions:

7 + 8681059 = 8681066
19 + 8681047 = 8681066
73 + 8680993 = 8681066
127 + 8680939 = 8681066
157 + 8680909 = 8681066
313 + 8680753 = 8681066
349 + 8680717 = 8681066
367 + 8680699 = 8681066

Showing the first eight; more decompositions exist.
