Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661284, here are decompositions:

3 + 8661281 = 8661284
31 + 8661253 = 8661284
43 + 8661241 = 8661284
61 + 8661223 = 8661284
67 + 8661217 = 8661284
103 + 8661181 = 8661284
223 + 8661061 = 8661284
241 + 8661043 = 8661284

Showing the first eight; more decompositions exist.
