Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561886, here are decompositions:

5 + 33561881 = 33561886
47 + 33561839 = 33561886
107 + 33561779 = 33561886
167 + 33561719 = 33561886
233 + 33561653 = 33561886
353 + 33561533 = 33561886
359 + 33561527 = 33561886
383 + 33561503 = 33561886

Showing the first eight; more decompositions exist.
