Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531568, here are decompositions:

41 + 33531527 = 33531568
89 + 33531479 = 33531568
101 + 33531467 = 33531568
137 + 33531431 = 33531568
179 + 33531389 = 33531568
269 + 33531299 = 33531568
401 + 33531167 = 33531568
491 + 33531077 = 33531568

Showing the first eight; more decompositions exist.
