Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537880, here are decompositions:

17 + 33537863 = 33537880
23 + 33537857 = 33537880
41 + 33537839 = 33537880
71 + 33537809 = 33537880
83 + 33537797 = 33537880
113 + 33537767 = 33537880
179 + 33537701 = 33537880
191 + 33537689 = 33537880

Showing the first eight; more decompositions exist.
