Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493218, here are decompositions:

7 + 33493211 = 33493218
47 + 33493171 = 33493218
61 + 33493157 = 33493218
79 + 33493139 = 33493218
97 + 33493121 = 33493218
137 + 33493081 = 33493218
331 + 33492887 = 33493218
347 + 33492871 = 33493218

Showing the first eight; more decompositions exist.
