Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481180, here are decompositions:

17 + 33481163 = 33481180
107 + 33481073 = 33481180
113 + 33481067 = 33481180
167 + 33481013 = 33481180
233 + 33480947 = 33481180
251 + 33480929 = 33481180
263 + 33480917 = 33481180
347 + 33480833 = 33481180

Showing the first eight; more decompositions exist.
