Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481578, here are decompositions:

7 + 33481571 = 33481578
29 + 33481549 = 33481578
71 + 33481507 = 33481578
79 + 33481499 = 33481578
107 + 33481471 = 33481578
149 + 33481429 = 33481578
181 + 33481397 = 33481578
211 + 33481367 = 33481578

Showing the first eight; more decompositions exist.
