Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579820, here are decompositions:

3 + 33579817 = 33579820
11 + 33579809 = 33579820
83 + 33579737 = 33579820
107 + 33579713 = 33579820
149 + 33579671 = 33579820
191 + 33579629 = 33579820
233 + 33579587 = 33579820
269 + 33579551 = 33579820

Showing the first eight; more decompositions exist.
