Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681462, here are decompositions:

61 + 8681401 = 8681462
103 + 8681359 = 8681462
151 + 8681311 = 8681462
199 + 8681263 = 8681462
211 + 8681251 = 8681462
241 + 8681221 = 8681462
271 + 8681191 = 8681462
331 + 8681131 = 8681462

Showing the first eight; more decompositions exist.
