Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489472, here are decompositions:

41 + 33489431 = 33489472
131 + 33489341 = 33489472
179 + 33489293 = 33489472
251 + 33489221 = 33489472
293 + 33489179 = 33489472
683 + 33488789 = 33489472
701 + 33488771 = 33489472
743 + 33488729 = 33489472

Showing the first eight; more decompositions exist.
