Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572972, here are decompositions:

31 + 33572941 = 33572972
61 + 33572911 = 33572972
109 + 33572863 = 33572972
193 + 33572779 = 33572972
229 + 33572743 = 33572972
271 + 33572701 = 33572972
439 + 33572533 = 33572972
619 + 33572353 = 33572972

Showing the first eight; more decompositions exist.
