Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500280, here are decompositions:

13 + 33500267 = 33500280
17 + 33500263 = 33500280
19 + 33500261 = 33500280
59 + 33500221 = 33500280
61 + 33500219 = 33500280
71 + 33500209 = 33500280
109 + 33500171 = 33500280
127 + 33500153 = 33500280

Showing the first eight; more decompositions exist.
