Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020288, here are decompositions:

19 + 1020269 = 1020288
29 + 1020259 = 1020288
41 + 1020247 = 1020288
131 + 1020157 = 1020288
151 + 1020137 = 1020288
179 + 1020109 = 1020288
211 + 1020077 = 1020288
229 + 1020059 = 1020288

Showing the first eight; more decompositions exist.
