Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529720, here are decompositions:

53 + 33529667 = 33529720
137 + 33529583 = 33529720
149 + 33529571 = 33529720
179 + 33529541 = 33529720
281 + 33529439 = 33529720
311 + 33529409 = 33529720
443 + 33529277 = 33529720
449 + 33529271 = 33529720

Showing the first eight; more decompositions exist.
