Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481840, here are decompositions:

3 + 33481837 = 33481840
23 + 33481817 = 33481840
71 + 33481769 = 33481840
83 + 33481757 = 33481840
89 + 33481751 = 33481840
101 + 33481739 = 33481840
263 + 33481577 = 33481840
269 + 33481571 = 33481840

Showing the first eight; more decompositions exist.
