Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632660, here are decompositions:

11 + 8632649 = 8632660
131 + 8632529 = 8632660
137 + 8632523 = 8632660
167 + 8632493 = 8632660
173 + 8632487 = 8632660
269 + 8632391 = 8632660
293 + 8632367 = 8632660
347 + 8632313 = 8632660

Showing the first eight; more decompositions exist.
