Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605020, here are decompositions:

3 + 33605017 = 33605020
131 + 33604889 = 33605020
179 + 33604841 = 33605020
263 + 33604757 = 33605020
467 + 33604553 = 33605020
503 + 33604517 = 33605020
509 + 33604511 = 33605020
773 + 33604247 = 33605020

Showing the first eight; more decompositions exist.
