Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553968, here are decompositions:

59 + 33553909 = 33553968
67 + 33553901 = 33553968
89 + 33553879 = 33553968
131 + 33553837 = 33553968
181 + 33553787 = 33553968
197 + 33553771 = 33553968
199 + 33553769 = 33553968
229 + 33553739 = 33553968

Showing the first eight; more decompositions exist.
