Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530780, here are decompositions:

7 + 33530773 = 33530780
67 + 33530713 = 33530780
79 + 33530701 = 33530780
103 + 33530677 = 33530780
163 + 33530617 = 33530780
211 + 33530569 = 33530780
223 + 33530557 = 33530780
229 + 33530551 = 33530780

Showing the first eight; more decompositions exist.
