Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487480, here are decompositions:

3 + 33487477 = 33487480
29 + 33487451 = 33487480
137 + 33487343 = 33487480
167 + 33487313 = 33487480
179 + 33487301 = 33487480
233 + 33487247 = 33487480
293 + 33487187 = 33487480
317 + 33487163 = 33487480

Showing the first eight; more decompositions exist.
