Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543820, here are decompositions:

17 + 33543803 = 33543820
29 + 33543791 = 33543820
47 + 33543773 = 33543820
59 + 33543761 = 33543820
131 + 33543689 = 33543820
179 + 33543641 = 33543820
281 + 33543539 = 33543820
311 + 33543509 = 33543820

Showing the first eight; more decompositions exist.
