Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481878, here are decompositions:

41 + 33481837 = 33481878
47 + 33481831 = 33481878
61 + 33481817 = 33481878
71 + 33481807 = 33481878
109 + 33481769 = 33481878
127 + 33481751 = 33481878
139 + 33481739 = 33481878
149 + 33481729 = 33481878

Showing the first eight; more decompositions exist.
