Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490972, here are decompositions:

23 + 33490949 = 33490972
83 + 33490889 = 33490972
131 + 33490841 = 33490972
191 + 33490781 = 33490972
443 + 33490529 = 33490972
509 + 33490463 = 33490972
563 + 33490409 = 33490972
701 + 33490271 = 33490972

Showing the first eight; more decompositions exist.
