Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487220, here are decompositions:

31 + 33487189 = 33487220
73 + 33487147 = 33487220
103 + 33487117 = 33487220
139 + 33487081 = 33487220
199 + 33487021 = 33487220
223 + 33486997 = 33487220
373 + 33486847 = 33487220
379 + 33486841 = 33487220

Showing the first eight; more decompositions exist.
