Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489428, here are decompositions:

67 + 33489361 = 33489428
79 + 33489349 = 33489428
109 + 33489319 = 33489428
277 + 33489151 = 33489428
331 + 33489097 = 33489428
829 + 33488599 = 33489428
859 + 33488569 = 33489428
919 + 33488509 = 33489428

Showing the first eight; more decompositions exist.
