Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049280, here are decompositions:

17 + 1049263 = 1049280
41 + 1049239 = 1049280
53 + 1049227 = 1049280
61 + 1049219 = 1049280
79 + 1049201 = 1049280
97 + 1049183 = 1049280
103 + 1049177 = 1049280
107 + 1049173 = 1049280

Showing the first eight; more decompositions exist.
