Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023280, here are decompositions:

3 + 1023277 = 1023280
17 + 1023263 = 1023280
23 + 1023257 = 1023280
53 + 1023227 = 1023280
59 + 1023221 = 1023280
107 + 1023173 = 1023280
113 + 1023167 = 1023280
173 + 1023107 = 1023280

Showing the first eight; more decompositions exist.
