Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506688, here are decompositions:

29 + 33506659 = 33506688
71 + 33506617 = 33506688
101 + 33506587 = 33506688
107 + 33506581 = 33506688
109 + 33506579 = 33506688
139 + 33506549 = 33506688
167 + 33506521 = 33506688
179 + 33506509 = 33506688

Showing the first eight; more decompositions exist.
