Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537990, here are decompositions:

19 + 33537971 = 33537990
29 + 33537961 = 33537990
71 + 33537919 = 33537990
127 + 33537863 = 33537990
151 + 33537839 = 33537990
181 + 33537809 = 33537990
193 + 33537797 = 33537990
223 + 33537767 = 33537990

Showing the first eight; more decompositions exist.
