Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487280, here are decompositions:

3 + 33487277 = 33487280
7 + 33487273 = 33487280
19 + 33487261 = 33487280
61 + 33487219 = 33487280
163 + 33487117 = 33487280
199 + 33487081 = 33487280
283 + 33486997 = 33487280
433 + 33486847 = 33487280

Showing the first eight; more decompositions exist.
