Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055428, here are decompositions:

5 + 1055423 = 1055428
29 + 1055399 = 1055428
41 + 1055387 = 1055428
107 + 1055321 = 1055428
167 + 1055261 = 1055428
197 + 1055231 = 1055428
239 + 1055189 = 1055428
389 + 1055039 = 1055428

Showing the first eight; more decompositions exist.
