Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537850, here are decompositions:

11 + 33537839 = 33537850
41 + 33537809 = 33537850
53 + 33537797 = 33537850
83 + 33537767 = 33537850
149 + 33537701 = 33537850
167 + 33537683 = 33537850
173 + 33537677 = 33537850
251 + 33537599 = 33537850

Showing the first eight; more decompositions exist.
