Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048280, here are decompositions:

7 + 1048273 = 1048280
19 + 1048261 = 1048280
61 + 1048219 = 1048280
67 + 1048213 = 1048280
151 + 1048129 = 1048280
157 + 1048123 = 1048280
229 + 1048051 = 1048280
271 + 1048009 = 1048280

Showing the first eight; more decompositions exist.
