Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661444, here are decompositions:

5 + 8661439 = 8661444
7 + 8661437 = 8661444
17 + 8661427 = 8661444
31 + 8661413 = 8661444
37 + 8661407 = 8661444
61 + 8661383 = 8661444
163 + 8661281 = 8661444
191 + 8661253 = 8661444

Showing the first eight; more decompositions exist.
