Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537900, here are decompositions:

37 + 33537863 = 33537900
43 + 33537857 = 33537900
61 + 33537839 = 33537900
103 + 33537797 = 33537900
131 + 33537769 = 33537900
191 + 33537709 = 33537900
199 + 33537701 = 33537900
211 + 33537689 = 33537900

Showing the first eight; more decompositions exist.
