Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661486, here are decompositions:

7 + 8661479 = 8661486
17 + 8661469 = 8661486
47 + 8661439 = 8661486
59 + 8661427 = 8661486
73 + 8661413 = 8661486
79 + 8661407 = 8661486
103 + 8661383 = 8661486
233 + 8661253 = 8661486

Showing the first eight; more decompositions exist.
