Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481856, here are decompositions:

3 + 33481853 = 33481856
19 + 33481837 = 33481856
73 + 33481783 = 33481856
97 + 33481759 = 33481856
103 + 33481753 = 33481856
127 + 33481729 = 33481856
229 + 33481627 = 33481856
307 + 33481549 = 33481856

Showing the first eight; more decompositions exist.
