Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609678, here are decompositions:

7 + 33609671 = 33609678
29 + 33609649 = 33609678
71 + 33609607 = 33609678
97 + 33609581 = 33609678
107 + 33609571 = 33609678
131 + 33609547 = 33609678
139 + 33609539 = 33609678
149 + 33609529 = 33609678

Showing the first eight; more decompositions exist.
