Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538428, here are decompositions:

5 + 538423 = 538428
17 + 538411 = 538428
29 + 538399 = 538428
31 + 538397 = 538428
61 + 538367 = 538428
71 + 538357 = 538428
97 + 538331 = 538428
127 + 538301 = 538428

Showing the first eight; more decompositions exist.
