Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519728, here are decompositions:

19 + 33519709 = 33519728
139 + 33519589 = 33519728
181 + 33519547 = 33519728
271 + 33519457 = 33519728
331 + 33519397 = 33519728
439 + 33519289 = 33519728
601 + 33519127 = 33519728
727 + 33519001 = 33519728

Showing the first eight; more decompositions exist.
