Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531628, here are decompositions:

17 + 33531611 = 33531628
41 + 33531587 = 33531628
101 + 33531527 = 33531628
149 + 33531479 = 33531628
197 + 33531431 = 33531628
239 + 33531389 = 33531628
281 + 33531347 = 33531628
359 + 33531269 = 33531628

Showing the first eight; more decompositions exist.
