Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681946, here are decompositions:

5 + 8681941 = 8681946
23 + 8681923 = 8681946
47 + 8681899 = 8681946
89 + 8681857 = 8681946
109 + 8681837 = 8681946
157 + 8681789 = 8681946
167 + 8681779 = 8681946
239 + 8681707 = 8681946

Showing the first eight; more decompositions exist.
