Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045040, here are decompositions:

13 + 1045027 = 1045040
19 + 1045021 = 1045040
37 + 1045003 = 1045040
43 + 1044997 = 1045040
109 + 1044931 = 1045040
151 + 1044889 = 1045040
163 + 1044877 = 1045040
181 + 1044859 = 1045040

Showing the first eight; more decompositions exist.
