Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587538, here are decompositions:

29 + 33587509 = 33587538
31 + 33587507 = 33587538
59 + 33587479 = 33587538
67 + 33587471 = 33587538
137 + 33587401 = 33587538
167 + 33587371 = 33587538
181 + 33587357 = 33587538
191 + 33587347 = 33587538

Showing the first eight; more decompositions exist.
