Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520138, here are decompositions:

11 + 33520127 = 33520138
107 + 33520031 = 33520138
347 + 33519791 = 33520138
389 + 33519749 = 33520138
479 + 33519659 = 33520138
521 + 33519617 = 33520138
599 + 33519539 = 33520138
719 + 33519419 = 33520138

Showing the first eight; more decompositions exist.
