Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530240, here are decompositions:

61 + 33530179 = 33530240
181 + 33530059 = 33530240
283 + 33529957 = 33530240
379 + 33529861 = 33530240
421 + 33529819 = 33530240
571 + 33529669 = 33530240
631 + 33529609 = 33530240
739 + 33529501 = 33530240

Showing the first eight; more decompositions exist.
