Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490974, here are decompositions:

47 + 33490927 = 33490974
67 + 33490907 = 33490974
131 + 33490843 = 33490974
157 + 33490817 = 33490974
173 + 33490801 = 33490974
193 + 33490781 = 33490974
197 + 33490777 = 33490974
211 + 33490763 = 33490974

Showing the first eight; more decompositions exist.
