Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493880, here are decompositions:

3 + 33493877 = 33493880
67 + 33493813 = 33493880
73 + 33493807 = 33493880
97 + 33493783 = 33493880
103 + 33493777 = 33493880
163 + 33493717 = 33493880
241 + 33493639 = 33493880
307 + 33493573 = 33493880

Showing the first eight; more decompositions exist.
