Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579990, here are decompositions:

29 + 33579961 = 33579990
71 + 33579919 = 33579990
83 + 33579907 = 33579990
137 + 33579853 = 33579990
149 + 33579841 = 33579990
163 + 33579827 = 33579990
167 + 33579823 = 33579990
173 + 33579817 = 33579990

Showing the first eight; more decompositions exist.
