Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489870, here are decompositions:

13 + 33489857 = 33489870
31 + 33489839 = 33489870
41 + 33489829 = 33489870
79 + 33489791 = 33489870
101 + 33489769 = 33489870
107 + 33489763 = 33489870
131 + 33489739 = 33489870
157 + 33489713 = 33489870

Showing the first eight; more decompositions exist.
