Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045028, here are decompositions:

7 + 1045021 = 1045028
31 + 1044997 = 1045028
97 + 1044931 = 1045028
139 + 1044889 = 1045028
151 + 1044877 = 1045028
181 + 1044847 = 1045028
277 + 1044751 = 1045028
331 + 1044697 = 1045028

Showing the first eight; more decompositions exist.
