Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487512, here are decompositions:

5 + 33487507 = 33487512
61 + 33487451 = 33487512
89 + 33487423 = 33487512
193 + 33487319 = 33487512
199 + 33487313 = 33487512
211 + 33487301 = 33487512
239 + 33487273 = 33487512
241 + 33487271 = 33487512

Showing the first eight; more decompositions exist.
