Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618620, here are decompositions:

43 + 33618577 = 33618620
127 + 33618493 = 33618620
181 + 33618439 = 33618620
199 + 33618421 = 33618620
241 + 33618379 = 33618620
307 + 33618313 = 33618620
313 + 33618307 = 33618620
331 + 33618289 = 33618620

Showing the first eight; more decompositions exist.
