Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487400, here are decompositions:

7 + 33487393 = 33487400
13 + 33487387 = 33487400
127 + 33487273 = 33487400
139 + 33487261 = 33487400
181 + 33487219 = 33487400
211 + 33487189 = 33487400
283 + 33487117 = 33487400
367 + 33487033 = 33487400

Showing the first eight; more decompositions exist.
