Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578972, here are decompositions:

3 + 33578969 = 33578972
61 + 33578911 = 33578972
109 + 33578863 = 33578972
199 + 33578773 = 33578972
211 + 33578761 = 33578972
223 + 33578749 = 33578972
313 + 33578659 = 33578972
331 + 33578641 = 33578972

Showing the first eight; more decompositions exist.
