Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508688, here are decompositions:

61 + 33508627 = 33508688
139 + 33508549 = 33508688
181 + 33508507 = 33508688
271 + 33508417 = 33508688
349 + 33508339 = 33508688
397 + 33508291 = 33508688
541 + 33508147 = 33508688
751 + 33507937 = 33508688

Showing the first eight; more decompositions exist.
