Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480072, here are decompositions:

19 + 33480053 = 33480072
29 + 33480043 = 33480072
71 + 33480001 = 33480072
83 + 33479989 = 33480072
89 + 33479983 = 33480072
163 + 33479909 = 33480072
193 + 33479879 = 33480072
211 + 33479861 = 33480072

Showing the first eight; more decompositions exist.
