Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615020, here are decompositions:

3 + 33615017 = 33615020
13 + 33615007 = 33615020
67 + 33614953 = 33615020
79 + 33614941 = 33615020
97 + 33614923 = 33615020
193 + 33614827 = 33615020
211 + 33614809 = 33615020
379 + 33614641 = 33615020

Showing the first eight; more decompositions exist.
