Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011280, here are decompositions:

3 + 1011277 = 1011280
41 + 1011239 = 1011280
47 + 1011233 = 1011280
59 + 1011221 = 1011280
89 + 1011191 = 1011280
113 + 1011167 = 1011280
173 + 1011107 = 1011280
251 + 1011029 = 1011280

Showing the first eight; more decompositions exist.
