Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048540, here are decompositions:

23 + 1048517 = 1048540
107 + 1048433 = 1048540
149 + 1048391 = 1048540
173 + 1048367 = 1048540
179 + 1048361 = 1048540
197 + 1048343 = 1048540
347 + 1048193 = 1048540
401 + 1048139 = 1048540

Showing the first eight; more decompositions exist.
