Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487998, here are decompositions:

29 + 33487969 = 33487998
97 + 33487901 = 33487998
139 + 33487859 = 33487998
151 + 33487847 = 33487998
179 + 33487819 = 33487998
227 + 33487771 = 33487998
239 + 33487759 = 33487998
241 + 33487757 = 33487998

Showing the first eight; more decompositions exist.
