Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605380, here are decompositions:

71 + 33605309 = 33605380
89 + 33605291 = 33605380
113 + 33605267 = 33605380
173 + 33605207 = 33605380
227 + 33605153 = 33605380
293 + 33605087 = 33605380
491 + 33604889 = 33605380
503 + 33604877 = 33605380

Showing the first eight; more decompositions exist.
