Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561900, here are decompositions:

19 + 33561881 = 33561900
23 + 33561877 = 33561900
61 + 33561839 = 33561900
83 + 33561817 = 33561900
101 + 33561799 = 33561900
131 + 33561769 = 33561900
149 + 33561751 = 33561900
157 + 33561743 = 33561900

Showing the first eight; more decompositions exist.
