Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049216, here are decompositions:

43 + 1049173 = 1049216
73 + 1049143 = 1049216
79 + 1049137 = 1049216
127 + 1049089 = 1049216
139 + 1049077 = 1049216
193 + 1049023 = 1049216
307 + 1048909 = 1049216
349 + 1048867 = 1049216

Showing the first eight; more decompositions exist.
