Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028238, here are decompositions:

7 + 1028231 = 1028238
17 + 1028221 = 1028238
31 + 1028207 = 1028238
37 + 1028201 = 1028238
47 + 1028191 = 1028238
89 + 1028149 = 1028238
97 + 1028141 = 1028238
109 + 1028129 = 1028238

Showing the first eight; more decompositions exist.
