Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487228, here are decompositions:

41 + 33487187 = 33487228
107 + 33487121 = 33487228
167 + 33487061 = 33487228
179 + 33487049 = 33487228
197 + 33487031 = 33487228
311 + 33486917 = 33487228
461 + 33486767 = 33487228
479 + 33486749 = 33487228

Showing the first eight; more decompositions exist.
