Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500178, here are decompositions:

7 + 33500171 = 33500178
67 + 33500111 = 33500178
71 + 33500107 = 33500178
139 + 33500039 = 33500178
167 + 33500011 = 33500178
181 + 33499997 = 33500178
251 + 33499927 = 33500178
269 + 33499909 = 33500178

Showing the first eight; more decompositions exist.
