Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521830, here are decompositions:

3 + 33521827 = 33521830
47 + 33521783 = 33521830
71 + 33521759 = 33521830
101 + 33521729 = 33521830
137 + 33521693 = 33521830
281 + 33521549 = 33521830
347 + 33521483 = 33521830
359 + 33521471 = 33521830

Showing the first eight; more decompositions exist.
