Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491072, here are decompositions:

31 + 33491041 = 33491072
73 + 33490999 = 33491072
229 + 33490843 = 33491072
271 + 33490801 = 33491072
379 + 33490693 = 33491072
499 + 33490573 = 33491072
619 + 33490453 = 33491072
691 + 33490381 = 33491072

Showing the first eight; more decompositions exist.
