Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523920, here are decompositions:

11 + 33523909 = 33523920
37 + 33523883 = 33523920
43 + 33523877 = 33523920
83 + 33523837 = 33523920
127 + 33523793 = 33523920
139 + 33523781 = 33523920
151 + 33523769 = 33523920
163 + 33523757 = 33523920

Showing the first eight; more decompositions exist.
