Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045280, here are decompositions:

3 + 1045277 = 1045280
7 + 1045273 = 1045280
43 + 1045237 = 1045280
97 + 1045183 = 1045280
127 + 1045153 = 1045280
151 + 1045129 = 1045280
157 + 1045123 = 1045280
163 + 1045117 = 1045280

Showing the first eight; more decompositions exist.
