Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489820, here are decompositions:

29 + 33489791 = 33489820
83 + 33489737 = 33489820
107 + 33489713 = 33489820
113 + 33489707 = 33489820
131 + 33489689 = 33489820
137 + 33489683 = 33489820
167 + 33489653 = 33489820
191 + 33489629 = 33489820

Showing the first eight; more decompositions exist.
