Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681424, here are decompositions:

23 + 8681401 = 8681424
47 + 8681377 = 8681424
61 + 8681363 = 8681424
67 + 8681357 = 8681424
83 + 8681341 = 8681424
107 + 8681317 = 8681424
113 + 8681311 = 8681424
137 + 8681287 = 8681424

Showing the first eight; more decompositions exist.
