Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487540, here are decompositions:

3 + 33487537 = 33487540
29 + 33487511 = 33487540
89 + 33487451 = 33487540
197 + 33487343 = 33487540
227 + 33487313 = 33487540
239 + 33487301 = 33487540
263 + 33487277 = 33487540
269 + 33487271 = 33487540

Showing the first eight; more decompositions exist.
