Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561982, here are decompositions:

5 + 33561977 = 33561982
23 + 33561959 = 33561982
29 + 33561953 = 33561982
53 + 33561929 = 33561982
71 + 33561911 = 33561982
101 + 33561881 = 33561982
131 + 33561851 = 33561982
239 + 33561743 = 33561982

Showing the first eight; more decompositions exist.
