Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623540, here are decompositions:

37 + 33623503 = 33623540
43 + 33623497 = 33623540
151 + 33623389 = 33623540
199 + 33623341 = 33623540
211 + 33623329 = 33623540
241 + 33623299 = 33623540
367 + 33623173 = 33623540
373 + 33623167 = 33623540

Showing the first eight; more decompositions exist.
