Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493278, here are decompositions:

37 + 33493241 = 33493278
61 + 33493217 = 33493278
67 + 33493211 = 33493278
107 + 33493171 = 33493278
139 + 33493139 = 33493278
157 + 33493121 = 33493278
197 + 33493081 = 33493278
229 + 33493049 = 33493278

Showing the first eight; more decompositions exist.
