Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472072, here are decompositions:

5 + 33472067 = 33472072
83 + 33471989 = 33472072
173 + 33471899 = 33472072
269 + 33471803 = 33472072
353 + 33471719 = 33472072
383 + 33471689 = 33472072
443 + 33471629 = 33472072
479 + 33471593 = 33472072

Showing the first eight; more decompositions exist.
