Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029280, here are decompositions:

3 + 1029277 = 1029280
17 + 1029263 = 1029280
29 + 1029251 = 1029280
71 + 1029209 = 1029280
89 + 1029191 = 1029280
101 + 1029179 = 1029280
113 + 1029167 = 1029280
167 + 1029113 = 1029280

Showing the first eight; more decompositions exist.
