Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008428, here are decompositions:

7 + 1008421 = 1008428
19 + 1008409 = 1008428
97 + 1008331 = 1008428
181 + 1008247 = 1008428
199 + 1008229 = 1008428
229 + 1008199 = 1008428
241 + 1008187 = 1008428
271 + 1008157 = 1008428

Showing the first eight; more decompositions exist.
