Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493158, here are decompositions:

5 + 33493153 = 33493158
19 + 33493139 = 33493158
37 + 33493121 = 33493158
109 + 33493049 = 33493158
241 + 33492917 = 33493158
269 + 33492889 = 33493158
271 + 33492887 = 33493158
311 + 33492847 = 33493158

Showing the first eight; more decompositions exist.
