Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661456, here are decompositions:

17 + 8661439 = 8661456
19 + 8661437 = 8661456
29 + 8661427 = 8661456
43 + 8661413 = 8661456
73 + 8661383 = 8661456
103 + 8661353 = 8661456
233 + 8661223 = 8661456
239 + 8661217 = 8661456

Showing the first eight; more decompositions exist.
