Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489880, here are decompositions:

3 + 33489877 = 33489880
23 + 33489857 = 33489880
41 + 33489839 = 33489880
89 + 33489791 = 33489880
167 + 33489713 = 33489880
173 + 33489707 = 33489880
191 + 33489689 = 33489880
197 + 33489683 = 33489880

Showing the first eight; more decompositions exist.
