Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489978, here are decompositions:

17 + 33489961 = 33489978
31 + 33489947 = 33489978
37 + 33489941 = 33489978
47 + 33489931 = 33489978
101 + 33489877 = 33489978
107 + 33489871 = 33489978
139 + 33489839 = 33489978
149 + 33489829 = 33489978

Showing the first eight; more decompositions exist.
