Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515880, here are decompositions:

17 + 33515863 = 33515880
19 + 33515861 = 33515880
31 + 33515849 = 33515880
43 + 33515837 = 33515880
67 + 33515813 = 33515880
107 + 33515773 = 33515880
109 + 33515771 = 33515880
173 + 33515707 = 33515880

Showing the first eight; more decompositions exist.
