Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493180, here are decompositions:

23 + 33493157 = 33493180
41 + 33493139 = 33493180
59 + 33493121 = 33493180
131 + 33493049 = 33493180
257 + 33492923 = 33493180
263 + 33492917 = 33493180
293 + 33492887 = 33493180
317 + 33492863 = 33493180

Showing the first eight; more decompositions exist.
