Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33492872, here are decompositions:

79 + 33492793 = 33492872
181 + 33492691 = 33492872
241 + 33492631 = 33492872
331 + 33492541 = 33492872
409 + 33492463 = 33492872
499 + 33492373 = 33492872
643 + 33492229 = 33492872
733 + 33492139 = 33492872

Showing the first eight; more decompositions exist.
