Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564880, here are decompositions:

3 + 33564877 = 33564880
113 + 33564767 = 33564880
149 + 33564731 = 33564880
227 + 33564653 = 33564880
389 + 33564491 = 33564880
521 + 33564359 = 33564880
647 + 33564233 = 33564880
683 + 33564197 = 33564880

Showing the first eight; more decompositions exist.
