Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661446, here are decompositions:

7 + 8661439 = 8661446
19 + 8661427 = 8661446
193 + 8661253 = 8661446
223 + 8661223 = 8661446
229 + 8661217 = 8661446
397 + 8661049 = 8661446
463 + 8660983 = 8661446
499 + 8660947 = 8661446

Showing the first eight; more decompositions exist.
