Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049642, here are decompositions:

3 + 1049639 = 1049642
19 + 1049623 = 1049642
31 + 1049611 = 1049642
43 + 1049599 = 1049642
73 + 1049569 = 1049642
109 + 1049533 = 1049642
163 + 1049479 = 1049642
229 + 1049413 = 1049642

Showing the first eight; more decompositions exist.
