Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530090, here are decompositions:

19 + 33530071 = 33530090
31 + 33530059 = 33530090
67 + 33530023 = 33530090
103 + 33529987 = 33530090
229 + 33529861 = 33530090
271 + 33529819 = 33530090
379 + 33529711 = 33530090
421 + 33529669 = 33530090

Showing the first eight; more decompositions exist.
