Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490938, here are decompositions:

11 + 33490927 = 33490938
31 + 33490907 = 33490938
97 + 33490841 = 33490938
137 + 33490801 = 33490938
157 + 33490781 = 33490938
191 + 33490747 = 33490938
311 + 33490627 = 33490938
331 + 33490607 = 33490938

Showing the first eight; more decompositions exist.
