Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049800, here are decompositions:

53 + 1049747 = 1049800
83 + 1049717 = 1049800
113 + 1049687 = 1049800
137 + 1049663 = 1049800
197 + 1049603 = 1049800
251 + 1049549 = 1049800
263 + 1049537 = 1049800
281 + 1049519 = 1049800

Showing the first eight; more decompositions exist.
