Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536638, here are decompositions:

5 + 536633 = 536638
17 + 536621 = 536638
29 + 536609 = 536638
107 + 536531 = 536638
191 + 536447 = 536638
197 + 536441 = 536638
239 + 536399 = 536638
281 + 536357 = 536638

Showing the first eight; more decompositions exist.
