Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028258, here are decompositions:

37 + 1028221 = 1028258
67 + 1028191 = 1028258
109 + 1028149 = 1028258
151 + 1028107 = 1028258
157 + 1028101 = 1028258
211 + 1028047 = 1028258
229 + 1028029 = 1028258
241 + 1028017 = 1028258

Showing the first eight; more decompositions exist.
