Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012458, here are decompositions:

11 + 1012447 = 1012458
19 + 1012439 = 1012458
37 + 1012421 = 1012458
47 + 1012411 = 1012458
59 + 1012399 = 1012458
61 + 1012397 = 1012458
79 + 1012379 = 1012458
89 + 1012369 = 1012458

Showing the first eight; more decompositions exist.
