Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620188, here are decompositions:

5 + 33620183 = 33620188
29 + 33620159 = 33620188
59 + 33620129 = 33620188
131 + 33620057 = 33620188
137 + 33620051 = 33620188
149 + 33620039 = 33620188
269 + 33619919 = 33620188
389 + 33619799 = 33620188

Showing the first eight; more decompositions exist.
