Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561870, here are decompositions:

19 + 33561851 = 33561870
31 + 33561839 = 33561870
53 + 33561817 = 33561870
71 + 33561799 = 33561870
101 + 33561769 = 33561870
103 + 33561767 = 33561870
127 + 33561743 = 33561870
151 + 33561719 = 33561870

Showing the first eight; more decompositions exist.
