Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025280, here are decompositions:

7 + 1025273 = 1025280
13 + 1025267 = 1025280
19 + 1025261 = 1025280
23 + 1025257 = 1025280
41 + 1025239 = 1025280
71 + 1025209 = 1025280
83 + 1025197 = 1025280
127 + 1025153 = 1025280

Showing the first eight; more decompositions exist.
