Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623840, here are decompositions:

7 + 33623833 = 33623840
43 + 33623797 = 33623840
139 + 33623701 = 33623840
199 + 33623641 = 33623840
241 + 33623599 = 33623840
277 + 33623563 = 33623840
337 + 33623503 = 33623840
421 + 33623419 = 33623840

Showing the first eight; more decompositions exist.
