Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045120, here are decompositions:

3 + 1045117 = 1045120
59 + 1045061 = 1045120
107 + 1045013 = 1045120
149 + 1044971 = 1045120
179 + 1044941 = 1045120
227 + 1044893 = 1045120
269 + 1044851 = 1045120
281 + 1044839 = 1045120

Showing the first eight; more decompositions exist.
