Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1054428, here are decompositions:

5 + 1054423 = 1054428
47 + 1054381 = 1054428
59 + 1054369 = 1054428
97 + 1054331 = 1054428
101 + 1054327 = 1054428
107 + 1054321 = 1054428
127 + 1054301 = 1054428
181 + 1054247 = 1054428

Showing the first eight; more decompositions exist.
