Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505868, here are decompositions:

79 + 33505789 = 33505868
349 + 33505519 = 33505868
421 + 33505447 = 33505868
607 + 33505261 = 33505868
691 + 33505177 = 33505868
751 + 33505117 = 33505868
811 + 33505057 = 33505868
829 + 33505039 = 33505868

Showing the first eight; more decompositions exist.
