Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490138, here are decompositions:

29 + 33490109 = 33490138
41 + 33490097 = 33490138
47 + 33490091 = 33490138
107 + 33490031 = 33490138
131 + 33490007 = 33490138
191 + 33489947 = 33490138
197 + 33489941 = 33490138
281 + 33489857 = 33490138

Showing the first eight; more decompositions exist.
