Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472868, here are decompositions:

19 + 33472849 = 33472868
97 + 33472771 = 33472868
109 + 33472759 = 33472868
199 + 33472669 = 33472868
229 + 33472639 = 33472868
601 + 33472267 = 33472868
631 + 33472237 = 33472868
661 + 33472207 = 33472868

Showing the first eight; more decompositions exist.
