Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490856, here are decompositions:

13 + 33490843 = 33490856
43 + 33490813 = 33490856
79 + 33490777 = 33490856
109 + 33490747 = 33490856
163 + 33490693 = 33490856
229 + 33490627 = 33490856
277 + 33490579 = 33490856
283 + 33490573 = 33490856

Showing the first eight; more decompositions exist.
