Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661546, here are decompositions:

17 + 8661529 = 8661546
37 + 8661509 = 8661546
59 + 8661487 = 8661546
67 + 8661479 = 8661546
107 + 8661439 = 8661546
109 + 8661437 = 8661546
139 + 8661407 = 8661546
163 + 8661383 = 8661546

Showing the first eight; more decompositions exist.
