Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557772, here are decompositions:

5 + 33557767 = 33557772
19 + 33557753 = 33557772
23 + 33557749 = 33557772
41 + 33557731 = 33557772
43 + 33557729 = 33557772
71 + 33557701 = 33557772
89 + 33557683 = 33557772
109 + 33557663 = 33557772

Showing the first eight; more decompositions exist.
