Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509664, here are decompositions:

5 + 33509659 = 33509664
17 + 33509647 = 33509664
31 + 33509633 = 33509664
47 + 33509617 = 33509664
61 + 33509603 = 33509664
103 + 33509561 = 33509664
137 + 33509527 = 33509664
163 + 33509501 = 33509664

Showing the first eight; more decompositions exist.
