Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527978, here are decompositions:

7 + 33527971 = 33527978
31 + 33527947 = 33527978
37 + 33527941 = 33527978
79 + 33527899 = 33527978
97 + 33527881 = 33527978
109 + 33527869 = 33527978
181 + 33527797 = 33527978
229 + 33527749 = 33527978

Showing the first eight; more decompositions exist.
