Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489040, here are decompositions:

107 + 33488933 = 33489040
149 + 33488891 = 33489040
173 + 33488867 = 33489040
251 + 33488789 = 33489040
269 + 33488771 = 33489040
293 + 33488747 = 33489040
311 + 33488729 = 33489040
353 + 33488687 = 33489040

Showing the first eight; more decompositions exist.
