Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530840, here are decompositions:

3 + 33530837 = 33530840
67 + 33530773 = 33530840
127 + 33530713 = 33530840
139 + 33530701 = 33530840
163 + 33530677 = 33530840
223 + 33530617 = 33530840
271 + 33530569 = 33530840
283 + 33530557 = 33530840

Showing the first eight; more decompositions exist.
