Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530778, here are decompositions:

5 + 33530773 = 33530778
19 + 33530759 = 33530778
37 + 33530741 = 33530778
101 + 33530677 = 33530778
181 + 33530597 = 33530778
227 + 33530551 = 33530778
241 + 33530537 = 33530778
331 + 33530447 = 33530778

Showing the first eight; more decompositions exist.
