Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493990, here are decompositions:

17 + 33493973 = 33493990
83 + 33493907 = 33493990
113 + 33493877 = 33493990
149 + 33493841 = 33493990
317 + 33493673 = 33493990
389 + 33493601 = 33493990
449 + 33493541 = 33493990
461 + 33493529 = 33493990

Showing the first eight; more decompositions exist.
