Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013428, here are decompositions:

29 + 1013399 = 1013428
107 + 1013321 = 1013428
137 + 1013291 = 1013428
149 + 1013279 = 1013428
179 + 1013249 = 1013428
191 + 1013237 = 1013428
419 + 1013009 = 1013428
431 + 1012997 = 1013428

Showing the first eight; more decompositions exist.
