Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487420, here are decompositions:

3 + 33487417 = 33487420
101 + 33487319 = 33487420
107 + 33487313 = 33487420
149 + 33487271 = 33487420
173 + 33487247 = 33487420
227 + 33487193 = 33487420
233 + 33487187 = 33487420
257 + 33487163 = 33487420

Showing the first eight; more decompositions exist.
