Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681504, here are decompositions:

31 + 8681473 = 8681504
37 + 8681467 = 8681504
103 + 8681401 = 8681504
127 + 8681377 = 8681504
163 + 8681341 = 8681504
193 + 8681311 = 8681504
241 + 8681263 = 8681504
283 + 8681221 = 8681504

Showing the first eight; more decompositions exist.
