Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490788, here are decompositions:

7 + 33490781 = 33490788
11 + 33490777 = 33490788
41 + 33490747 = 33490788
151 + 33490637 = 33490788
181 + 33490607 = 33490788
241 + 33490547 = 33490788
251 + 33490537 = 33490788
269 + 33490519 = 33490788

Showing the first eight; more decompositions exist.
