Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555638, here are decompositions:

139 + 33555499 = 33555638
157 + 33555481 = 33555638
199 + 33555439 = 33555638
241 + 33555397 = 33555638
349 + 33555289 = 33555638
367 + 33555271 = 33555638
379 + 33555259 = 33555638
397 + 33555241 = 33555638

Showing the first eight; more decompositions exist.
