Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057280, here are decompositions:

31 + 1057249 = 1057280
43 + 1057237 = 1057280
61 + 1057219 = 1057280
97 + 1057183 = 1057280
151 + 1057129 = 1057280
163 + 1057117 = 1057280
193 + 1057087 = 1057280
229 + 1057051 = 1057280

Showing the first eight; more decompositions exist.
