Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049842, here are decompositions:

5 + 1049837 = 1049842
179 + 1049663 = 1049842
239 + 1049603 = 1049842
293 + 1049549 = 1049842
359 + 1049483 = 1049842
383 + 1049459 = 1049842
503 + 1049339 = 1049842
509 + 1049333 = 1049842

Showing the first eight; more decompositions exist.
