Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480978, here are decompositions:

7 + 33480971 = 33480978
31 + 33480947 = 33480978
61 + 33480917 = 33480978
127 + 33480851 = 33480978
149 + 33480829 = 33480978
151 + 33480827 = 33480978
191 + 33480787 = 33480978
197 + 33480781 = 33480978

Showing the first eight; more decompositions exist.
