Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048538, here are decompositions:

31 + 1048507 = 1048538
151 + 1048387 = 1048538
181 + 1048357 = 1048538
229 + 1048309 = 1048538
277 + 1048261 = 1048538
349 + 1048189 = 1048538
409 + 1048129 = 1048538
487 + 1048051 = 1048538

Showing the first eight; more decompositions exist.
