Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538988, here are decompositions:

37 + 33538951 = 33538988
97 + 33538891 = 33538988
229 + 33538759 = 33538988
277 + 33538711 = 33538988
349 + 33538639 = 33538988
409 + 33538579 = 33538988
541 + 33538447 = 33538988
547 + 33538441 = 33538988

Showing the first eight; more decompositions exist.
