Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661676, here are decompositions:

3 + 8661673 = 8661676
47 + 8661629 = 8661676
53 + 8661623 = 8661676
167 + 8661509 = 8661676
197 + 8661479 = 8661676
239 + 8661437 = 8661676
263 + 8661413 = 8661676
269 + 8661407 = 8661676

Showing the first eight; more decompositions exist.
