Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481918, here are decompositions:

5 + 33481913 = 33481918
101 + 33481817 = 33481918
149 + 33481769 = 33481918
167 + 33481751 = 33481918
179 + 33481739 = 33481918
347 + 33481571 = 33481918
419 + 33481499 = 33481918
521 + 33481397 = 33481918

Showing the first eight; more decompositions exist.
