Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561830, here are decompositions:

13 + 33561817 = 33561830
31 + 33561799 = 33561830
61 + 33561769 = 33561830
79 + 33561751 = 33561830
151 + 33561679 = 33561830
157 + 33561673 = 33561830
223 + 33561607 = 33561830
271 + 33561559 = 33561830

Showing the first eight; more decompositions exist.
