Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681444, here are decompositions:

43 + 8681401 = 8681444
67 + 8681377 = 8681444
103 + 8681341 = 8681444
127 + 8681317 = 8681444
157 + 8681287 = 8681444
181 + 8681263 = 8681444
193 + 8681251 = 8681444
223 + 8681221 = 8681444

Showing the first eight; more decompositions exist.
