Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661634, here are decompositions:

5 + 8661629 = 8661634
11 + 8661623 = 8661634
53 + 8661581 = 8661634
173 + 8661461 = 8661634
197 + 8661437 = 8661634
227 + 8661407 = 8661634
251 + 8661383 = 8661634
281 + 8661353 = 8661634

Showing the first eight; more decompositions exist.
