Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537918, here are decompositions:

19 + 33537899 = 33537918
61 + 33537857 = 33537918
79 + 33537839 = 33537918
109 + 33537809 = 33537918
149 + 33537769 = 33537918
151 + 33537767 = 33537918
229 + 33537689 = 33537918
241 + 33537677 = 33537918

Showing the first eight; more decompositions exist.
