Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505880, here are decompositions:

13 + 33505867 = 33505880
103 + 33505777 = 33505880
157 + 33505723 = 33505880
307 + 33505573 = 33505880
313 + 33505567 = 33505880
337 + 33505543 = 33505880
433 + 33505447 = 33505880
439 + 33505441 = 33505880

Showing the first eight; more decompositions exist.
