Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557868, here are decompositions:

31 + 33557837 = 33557868
41 + 33557827 = 33557868
59 + 33557809 = 33557868
61 + 33557807 = 33557868
79 + 33557789 = 33557868
101 + 33557767 = 33557868
131 + 33557737 = 33557868
137 + 33557731 = 33557868

Showing the first eight; more decompositions exist.
