Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489388, here are decompositions:

11 + 33489377 = 33489388
47 + 33489341 = 33489388
131 + 33489257 = 33489388
167 + 33489221 = 33489388
521 + 33488867 = 33489388
599 + 33488789 = 33489388
617 + 33488771 = 33489388
641 + 33488747 = 33489388

Showing the first eight; more decompositions exist.
