Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489642, here are decompositions:

13 + 33489629 = 33489642
19 + 33489623 = 33489642
23 + 33489619 = 33489642
29 + 33489613 = 33489642
31 + 33489611 = 33489642
59 + 33489583 = 33489642
73 + 33489569 = 33489642
83 + 33489559 = 33489642

Showing the first eight; more decompositions exist.
