Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505780, here are decompositions:

3 + 33505777 = 33505780
29 + 33505751 = 33505780
149 + 33505631 = 33505780
179 + 33505601 = 33505780
233 + 33505547 = 33505780
281 + 33505499 = 33505780
419 + 33505361 = 33505780
443 + 33505337 = 33505780

Showing the first eight; more decompositions exist.
