Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472040, here are decompositions:

31 + 33472009 = 33472040
61 + 33471979 = 33472040
67 + 33471973 = 33472040
229 + 33471811 = 33472040
241 + 33471799 = 33472040
271 + 33471769 = 33472040
307 + 33471733 = 33472040
331 + 33471709 = 33472040

Showing the first eight; more decompositions exist.
