Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043638, here are decompositions:

41 + 1043597 = 1043638
47 + 1043591 = 1043638
107 + 1043531 = 1043638
137 + 1043501 = 1043638
149 + 1043489 = 1043638
269 + 1043369 = 1043638
347 + 1043291 = 1043638
359 + 1043279 = 1043638

Showing the first eight; more decompositions exist.
