Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044642, here are decompositions:

13 + 1044629 = 1044642
23 + 1044619 = 1044642
29 + 1044613 = 1044642
59 + 1044583 = 1044642
73 + 1044569 = 1044642
83 + 1044559 = 1044642
113 + 1044529 = 1044642
163 + 1044479 = 1044642

Showing the first eight; more decompositions exist.
