Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681064, here are decompositions:

5 + 8681059 = 8681064
17 + 8681047 = 8681064
43 + 8681021 = 8681064
61 + 8681003 = 8681064
71 + 8680993 = 8681064
113 + 8680951 = 8681064
157 + 8680907 = 8681064
163 + 8680901 = 8681064

Showing the first eight; more decompositions exist.
