Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519972, here are decompositions:

23 + 33519949 = 33519972
29 + 33519943 = 33519972
43 + 33519929 = 33519972
179 + 33519793 = 33519972
181 + 33519791 = 33519972
223 + 33519749 = 33519972
263 + 33519709 = 33519972
313 + 33519659 = 33519972

Showing the first eight; more decompositions exist.
