Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048428, here are decompositions:

5 + 1048423 = 1048428
37 + 1048391 = 1048428
41 + 1048387 = 1048428
61 + 1048367 = 1048428
67 + 1048361 = 1048428
71 + 1048357 = 1048428
137 + 1048291 = 1048428
167 + 1048261 = 1048428

Showing the first eight; more decompositions exist.
