Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511988, here are decompositions:

127 + 33511861 = 33511988
199 + 33511789 = 33511988
271 + 33511717 = 33511988
379 + 33511609 = 33511988
439 + 33511549 = 33511988
457 + 33511531 = 33511988
541 + 33511447 = 33511988
691 + 33511297 = 33511988

Showing the first eight; more decompositions exist.
