Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578620, here are decompositions:

3 + 33578617 = 33578620
113 + 33578507 = 33578620
137 + 33578483 = 33578620
191 + 33578429 = 33578620
197 + 33578423 = 33578620
233 + 33578387 = 33578620
347 + 33578273 = 33578620
353 + 33578267 = 33578620

Showing the first eight; more decompositions exist.
