Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620380, here are decompositions:

23 + 33620357 = 33620380
29 + 33620351 = 33620380
179 + 33620201 = 33620380
191 + 33620189 = 33620380
197 + 33620183 = 33620380
251 + 33620129 = 33620380
401 + 33619979 = 33620380
461 + 33619919 = 33620380

Showing the first eight; more decompositions exist.
