Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493720, here are decompositions:

3 + 33493717 = 33493720
47 + 33493673 = 33493720
101 + 33493619 = 33493720
107 + 33493613 = 33493720
179 + 33493541 = 33493720
191 + 33493529 = 33493720
347 + 33493373 = 33493720
467 + 33493253 = 33493720

Showing the first eight; more decompositions exist.
