Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681492, here are decompositions:

3 + 8681489 = 8681492
19 + 8681473 = 8681492
151 + 8681341 = 8681492
181 + 8681311 = 8681492
229 + 8681263 = 8681492
241 + 8681251 = 8681492
271 + 8681221 = 8681492
433 + 8681059 = 8681492

Showing the first eight; more decompositions exist.
