Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025258, here are decompositions:

19 + 1025239 = 1025258
61 + 1025197 = 1025258
97 + 1025161 = 1025258
109 + 1025149 = 1025258
139 + 1025119 = 1025258
211 + 1025047 = 1025258
229 + 1025029 = 1025258
271 + 1024987 = 1025258

Showing the first eight; more decompositions exist.
