Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523520, here are decompositions:

67 + 33523453 = 33523520
73 + 33523447 = 33523520
97 + 33523423 = 33523520
109 + 33523411 = 33523520
139 + 33523381 = 33523520
193 + 33523327 = 33523520
229 + 33523291 = 33523520
379 + 33523141 = 33523520

Showing the first eight; more decompositions exist.
