Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490940, here are decompositions:

13 + 33490927 = 33490940
97 + 33490843 = 33490940
127 + 33490813 = 33490940
139 + 33490801 = 33490940
163 + 33490777 = 33490940
193 + 33490747 = 33490940
313 + 33490627 = 33490940
337 + 33490603 = 33490940

Showing the first eight; more decompositions exist.
