Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518288, here are decompositions:

19 + 33518269 = 33518288
79 + 33518209 = 33518288
151 + 33518137 = 33518288
157 + 33518131 = 33518288
241 + 33518047 = 33518288
277 + 33518011 = 33518288
367 + 33517921 = 33518288
409 + 33517879 = 33518288

Showing the first eight; more decompositions exist.
