Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553988, here are decompositions:

19 + 33553969 = 33553988
79 + 33553909 = 33553988
109 + 33553879 = 33553988
151 + 33553837 = 33553988
229 + 33553759 = 33553988
241 + 33553747 = 33553988
331 + 33553657 = 33553988
337 + 33553651 = 33553988

Showing the first eight; more decompositions exist.
