Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551180, here are decompositions:

67 + 33551113 = 33551180
73 + 33551107 = 33551180
127 + 33551053 = 33551180
139 + 33551041 = 33551180
199 + 33550981 = 33551180
241 + 33550939 = 33551180
331 + 33550849 = 33551180
349 + 33550831 = 33551180

Showing the first eight; more decompositions exist.
