Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681460, here are decompositions:

13 + 8681447 = 8681460
31 + 8681429 = 8681460
59 + 8681401 = 8681460
83 + 8681377 = 8681460
97 + 8681363 = 8681460
101 + 8681359 = 8681460
103 + 8681357 = 8681460
149 + 8681311 = 8681460

Showing the first eight; more decompositions exist.
