Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481240, here are decompositions:

47 + 33481193 = 33481240
53 + 33481187 = 33481240
167 + 33481073 = 33481240
173 + 33481067 = 33481240
227 + 33481013 = 33481240
263 + 33480977 = 33481240
269 + 33480971 = 33481240
293 + 33480947 = 33481240

Showing the first eight; more decompositions exist.
