Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481920, here are decompositions:

7 + 33481913 = 33481920
11 + 33481909 = 33481920
37 + 33481883 = 33481920
67 + 33481853 = 33481920
83 + 33481837 = 33481920
89 + 33481831 = 33481920
103 + 33481817 = 33481920
113 + 33481807 = 33481920

Showing the first eight; more decompositions exist.
