Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541830, here are decompositions:

11 + 33541819 = 33541830
13 + 33541817 = 33541830
29 + 33541801 = 33541830
59 + 33541771 = 33541830
61 + 33541769 = 33541830
73 + 33541757 = 33541830
97 + 33541733 = 33541830
107 + 33541723 = 33541830

Showing the first eight; more decompositions exist.
