Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527728, here are decompositions:

29 + 33527699 = 33527728
131 + 33527597 = 33527728
197 + 33527531 = 33527728
239 + 33527489 = 33527728
257 + 33527471 = 33527728
281 + 33527447 = 33527728
317 + 33527411 = 33527728
389 + 33527339 = 33527728

Showing the first eight; more decompositions exist.
