Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481864, here are decompositions:

11 + 33481853 = 33481864
47 + 33481817 = 33481864
107 + 33481757 = 33481864
113 + 33481751 = 33481864
293 + 33481571 = 33481864
467 + 33481397 = 33481864
503 + 33481361 = 33481864
617 + 33481247 = 33481864

Showing the first eight; more decompositions exist.
