Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490772, here are decompositions:

79 + 33490693 = 33490772
193 + 33490579 = 33490772
199 + 33490573 = 33490772
379 + 33490393 = 33490772
421 + 33490351 = 33490772
571 + 33490201 = 33490772
769 + 33490003 = 33490772
811 + 33489961 = 33490772

Showing the first eight; more decompositions exist.
