Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681466, here are decompositions:

19 + 8681447 = 8681466
37 + 8681429 = 8681466
89 + 8681377 = 8681466
97 + 8681369 = 8681466
103 + 8681363 = 8681466
107 + 8681359 = 8681466
109 + 8681357 = 8681466
149 + 8681317 = 8681466

Showing the first eight; more decompositions exist.
