Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681322, here are decompositions:

5 + 8681317 = 8681322
11 + 8681311 = 8681322
31 + 8681291 = 8681322
59 + 8681263 = 8681322
71 + 8681251 = 8681322
79 + 8681243 = 8681322
101 + 8681221 = 8681322
109 + 8681213 = 8681322

Showing the first eight; more decompositions exist.
