Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530388, here are decompositions:

19 + 33530369 = 33530388
29 + 33530359 = 33530388
41 + 33530347 = 33530388
61 + 33530327 = 33530388
79 + 33530309 = 33530388
109 + 33530279 = 33530388
127 + 33530261 = 33530388
139 + 33530249 = 33530388

Showing the first eight; more decompositions exist.
