Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481490, here are decompositions:

19 + 33481471 = 33481490
61 + 33481429 = 33481490
67 + 33481423 = 33481490
139 + 33481351 = 33481490
151 + 33481339 = 33481490
181 + 33481309 = 33481490
199 + 33481291 = 33481490
331 + 33481159 = 33481490

Showing the first eight; more decompositions exist.
