Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026428, here are decompositions:

37 + 1026391 = 1026428
97 + 1026331 = 1026428
199 + 1026229 = 1026428
211 + 1026217 = 1026428
229 + 1026199 = 1026428
367 + 1026061 = 1026428
397 + 1026031 = 1026428
499 + 1025929 = 1026428

Showing the first eight; more decompositions exist.
