Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523980, here are decompositions:

11 + 33523969 = 33523980
13 + 33523967 = 33523980
29 + 33523951 = 33523980
47 + 33523933 = 33523980
59 + 33523921 = 33523980
71 + 33523909 = 33523980
97 + 33523883 = 33523980
103 + 33523877 = 33523980

Showing the first eight; more decompositions exist.
