Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620388, here are decompositions:

7 + 33620381 = 33620388
17 + 33620371 = 33620388
31 + 33620357 = 33620388
37 + 33620351 = 33620388
47 + 33620341 = 33620388
89 + 33620299 = 33620388
149 + 33620239 = 33620388
167 + 33620221 = 33620388

Showing the first eight; more decompositions exist.
