Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505648, here are decompositions:

17 + 33505631 = 33505648
47 + 33505601 = 33505648
101 + 33505547 = 33505648
149 + 33505499 = 33505648
311 + 33505337 = 33505648
347 + 33505301 = 33505648
401 + 33505247 = 33505648
419 + 33505229 = 33505648

Showing the first eight; more decompositions exist.
