Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490842, here are decompositions:

29 + 33490813 = 33490842
41 + 33490801 = 33490842
61 + 33490781 = 33490842
79 + 33490763 = 33490842
149 + 33490693 = 33490842
239 + 33490603 = 33490842
263 + 33490579 = 33490842
269 + 33490573 = 33490842

Showing the first eight; more decompositions exist.
