Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472986, here are decompositions:

73 + 33472913 = 33472986
83 + 33472903 = 33472986
137 + 33472849 = 33472986
163 + 33472823 = 33472986
199 + 33472787 = 33472986
227 + 33472759 = 33472986
263 + 33472723 = 33472986
293 + 33472693 = 33472986

Showing the first eight; more decompositions exist.
