Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519840, here are decompositions:

47 + 33519793 = 33519840
71 + 33519769 = 33519840
89 + 33519751 = 33519840
113 + 33519727 = 33519840
131 + 33519709 = 33519840
181 + 33519659 = 33519840
197 + 33519643 = 33519840
223 + 33519617 = 33519840

Showing the first eight; more decompositions exist.
