Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038642, here are decompositions:

5 + 1038637 = 1038642
13 + 1038629 = 1038642
19 + 1038623 = 1038642
23 + 1038619 = 1038642
41 + 1038601 = 1038642
43 + 1038599 = 1038642
53 + 1038589 = 1038642
79 + 1038563 = 1038642

Showing the first eight; more decompositions exist.
