Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048438, here are decompositions:

5 + 1048433 = 1048438
47 + 1048391 = 1048438
71 + 1048367 = 1048438
311 + 1048127 = 1048438
389 + 1048049 = 1048438
431 + 1048007 = 1048438
449 + 1047989 = 1048438
467 + 1047971 = 1048438

Showing the first eight; more decompositions exist.
