Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509972, here are decompositions:

3 + 33509969 = 33509972
43 + 33509929 = 33509972
79 + 33509893 = 33509972
151 + 33509821 = 33509972
229 + 33509743 = 33509972
313 + 33509659 = 33509972
571 + 33509401 = 33509972
619 + 33509353 = 33509972

Showing the first eight; more decompositions exist.
