Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509900, here are decompositions:

7 + 33509893 = 33509900
79 + 33509821 = 33509900
97 + 33509803 = 33509900
157 + 33509743 = 33509900
241 + 33509659 = 33509900
283 + 33509617 = 33509900
331 + 33509569 = 33509900
373 + 33509527 = 33509900

Showing the first eight; more decompositions exist.
