Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489972, here are decompositions:

11 + 33489961 = 33489972
29 + 33489943 = 33489972
31 + 33489941 = 33489972
41 + 33489931 = 33489972
71 + 33489901 = 33489972
101 + 33489871 = 33489972
181 + 33489791 = 33489972
233 + 33489739 = 33489972

Showing the first eight; more decompositions exist.
