Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523900, here are decompositions:

17 + 33523883 = 33523900
23 + 33523877 = 33523900
71 + 33523829 = 33523900
101 + 33523799 = 33523900
107 + 33523793 = 33523900
131 + 33523769 = 33523900
149 + 33523751 = 33523900
173 + 33523727 = 33523900

Showing the first eight; more decompositions exist.
