Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620500, here are decompositions:

29 + 33620471 = 33620500
41 + 33620459 = 33620500
71 + 33620429 = 33620500
113 + 33620387 = 33620500
149 + 33620351 = 33620500
197 + 33620303 = 33620500
311 + 33620189 = 33620500
317 + 33620183 = 33620500

Showing the first eight; more decompositions exist.
